Ice And The Density Of Water
- Ph.D., Biomedical Sciences, University of Tennessee at Knoxville
- B.A., Physics and Mathematics, Hastings College
Why does ice float on top of the water, rather than sink like most solids? There are two parts to the answer to this question. First, let’s take a look at why anything floats. Then, let’s examine why ice floats on top of liquid water, instead of sinking to the bottom.
Is Chemistry Required For Medicine
Completing science pre-requisites during high school or your undergraduate degree is important, as it’s much harder to complete these pre-requisites after graduation. Remember, choosing high-level mathematics, chemistry, physics, biology and English will stand you in good stead as you study medicine.
Test Tube Or Chemical Reactor
As everyone can probably see, chemicals, their beneficial properties, and the processes for their production must be identified, investigated, tested, and then used to our advantage. When we consider that, if each one of ourselves consumes a chemical product in a year be it acylpyrine, soap or petrol even if it is only 10 tablets, 1 kilogram or 1,000 litres, then the quantities of these products required for the 333 million people of our country are very large indeed and have to be produced somewhere and in some facility.
Chemistry of this scale cannot be conducted in any test tubes, but in complex facilities requiring proper and responsible management, highly skilled operators and the necessary supervision.
Among other things, the economic level of any country is measured by its industrial production, which naturally includes the chemical industry. Doing business in the chemical industry needs to be supported by a legislative framework, strict regulations and clear rules. At the same time, it is vital to evaluate processes leading to the main product of chemical production.
The actual chemical transformation of molecules into the target products can, and usually does, generate by-products in chemical reactors, and therefore there is a part of the equipment in each technology that is aimed at the separation of the resulting mixture. Waste treatment is therefore often unimaginable without further downstream chemical processes.

Chemistry In Everyday Life
If you are studying chemistry then you must have wondered about the importance of chemistry in everyday life. Chemistry is the branch of science which deals with the investigation of the properties and changes of matter. From the way how our body exchanges oxygen to how our universe was created, all have a side of chemistry associated with it.
Heavy Water Ice Sinks
However, not all water ice floats on regular water. Ice made using heavy water, which contains the hydrogen isotope deuterium, sinks in regular water. Hydrogen bonding still occurs, but it’s not enough to offset the mass difference between normal and heavy water. Heavy water ice sinks in heavy water.

Chemistry Is A Physical Science
Chemistry is typically considered a physical science, as defined by the Encyclopedia Britannica, because the study of chemistry does not involve living things. Most of the chemistry involved in research and development, such as making new products and materials for customers, falls within this purview.
But the distinction as a physical science becomes a bit blurry in the case of biochemistry, which explores the chemistry of living things, according to the Biochemical Society. The chemicals and chemical processes studied by biochemists are not technically considered “living,” but understanding them is important to understanding how life works.
What Is Chemistry And Examples
The definition of chemistry is a branch of science that deals with the form and properties of matter and substances or the interaction between individuals. An example of chemistry is the study of protons and neutrons. An example of chemistry is the feeling of affection and attraction between a couple. noun.

The Image Of Chemistry In The Media
For a relatively long time, we have been witnessing that small groups of our countrymen have the right to speak on behalf of all of us about the harmfulness or danger of chemistry, the chemical industry and its products. These people spread the fear of chemistry, chemophobia, around them, and they also receive a lot of space in the tabloid media.
The campaigns against the chemical manufacturers are often purpose-driven, because there is global competition in this sector of industry too. The risks of chemical processes are being constantly reduced as technical information and a deep understanding of them is gathered. Nevertheless, human failure, as it is often referred to rather euphemistically, can never be 100% prevented.
Statistically, only a very small number of serious accidents occur annually in US directly in chemical production. Of course, we can think of entrusting the control of processes to computer systems however, then a computer failure or an error in the control program can also have fatal consequences. Lowering the probability of a potential accident, though, is very costly.
In the following, we want to talk about the role of chemistry in human life so we can better understand how chemistry is used in everyday life.
What Is Precipitation Reaction
Many chemical reactions occur in our daily lives. Common examples of such reactions are burning, corrosion, cooking of food and digestion. One important class of chemical reactions are precipitation reactions. In such reactions, two different soluble salts combine to form two products. One of these products is insoluble in the solution and is precipitated out .
Precipitation Reaction Definition and Meaning
The term precipitation reaction can be defined as a chemical reaction occurring in an aqueous solution where two ionic bonds combine, resulting in the formation of an insoluble salt. These insoluble salts formed in precipitation reactions are called precipitates. Precipitation reactions are usually double displacement reactions involving the production of a solid form residue called the precipitate. These reactions also occur when two or more solutions with different salts are combined, resulting in the formation of insoluble salts that precipitate out of the solution.
One of the best examples of precipitation reactions is the chemical reaction between potassium chloride and silver nitrate, in which solid silver chloride is precipitated out. This is the insoluble salt formed as a product of the precipitation reaction. The chemical equation for this precipitation reaction is provided below.
AgNO3 + KCl AgCl + KNO3
2KOH + CaCl2-Ca2 + 2KCl
Some more examples of chemical equations of on precipitation reaction are as below-
AgNO3 + NaCl – AgCl + NaNO3

Useful Examples Of Inorganic Chemistry In Everyday Life
- Post author
With the advancement of technology, experts have been able to develop science and create innovation in the name of improving human life. One of the fields affected by it in chemistry. In the past, human relied only on organic chemistry where all the sources of chemicals come from nature and living being.
In modern life, there are also many inorganic compound made synthetically in laboratory and just occur in nature. Chemists develop these chemicals to make up the lack of functions in organic compound or to press the cost. Below are some examples of inorganic chemistry in everyday life.
Many cleaning agents such as soap, detergent, floor cleaner, and glass cleaner contain inorganic compound either as solvent, cleaner itself, or bubble producer. Even the coloring of these products contain inorganic coloring such as CI pigment. Moreover, these chemicals are in the material together with organic compound.
These compounds can be very harsh like causing irritation, burning skin, dry patches and other side effects. That is why it is best not to get in contact to them directly unless it is a body or hand soap that contain milder chemical inside them.

The Expiration Date On Bottled Drinking Water:
Have you ever wondered why there is an expiration date on a bottle of drinking water, after all, it is just water isnt it? Well most of us havent even noticed that there is, in fact, an expiration date on that bottle. The idea behind instilling an expiration on bottled drinking water is to standardize the packaging quality of it.
What the actual expiration date signifies is if the expiration date is up, the taste of the water will be different as there is a chance of the chemicals in the packaging material ruining the quality of water.

Analytical Chemistry In Pharmacy Application
Commonly, analytical chemistry study is really applicable in pharmacy area. It has been used since long time ago for many purposes. The application areas include quality checking of compound from inorganic compound, organic compound, chemical products, drugs and many more.
In the pharmacy discipline perspective, analytical is the science study that gives the idea about compound separation, identification and quantification which are beneficial for some pharmacy measurement process like bioavailability of drugs. Analytical study can also be used in the purifying process during the synthesis of drugs and identifying the drug metabolic pathways. Herere some great advantages of analytical study in the pharmaceutical field.
1. Determining Self-Life of Compound
Self-life is the time period until that kind of compound will be fit for use. In term of drug, this means the time needed for 90% of the drug containment to keep fit after its being produced. Its the expiry date which is usually marked on every medicine products. We know that in pharmacy industry, medicine is stored in the refrigerator or the darker places to keep its self-life.
2. Determining Adulterants
3. Dissolution in Drugs
4. Qualitative and Quantitative Analysis
Analytical chemistry can also be used in the medical chemistry for the qualitative and quantitative analysis.
They’re All Around Us
Here are examples of organic chemistry at work:
- Polymers consist of long chains and branches of molecules. Common polymers you encounter every day are organic molecules. Examples include nylon, acrylic, PVC, polycarbonate, cellulose, and polyethylene.
- Petrochemicals are chemicals derived from crude oil or petroleum. Fractional distillation separates the raw material into organic compounds according to their different boiling points. Examples include gasoline, plastics, detergents, dyes, food additives, natural gas, and medicines.
- Although both are used for cleaning, soap and detergent are two different examples of organic chemistry. Soap is made by the saponification reaction, which reacts to hydroxide with an organic molecule to produce glycerol and crude soap. While soap is an emulsifier, detergents tackle oily, greasy soiling mainly because they are surfactants, which lower the surface tension of the water and increase the solubility of organic compounds.
- Whether a perfume fragrance comes from a flower or a lab, the molecules you smell and enjoy are an example of organic chemistry.
- The cosmetics industry is a lucrative sector of organic chemistry. Chemists examine changes in the skin in response to metabolic and environmental factors, formulate products to address skin problems and enhance beauty, and analyze how cosmetics interact with the skin and other products.

Analytical Chemistry Application In Agriculture
Agriculture also uses the analytical chemistry in many areas. Herere the three major applications of analytical chemistry in the agriculture field.
5. Soil Testing
The analytical chemistry is also important for the soil test process in the agriculture field. The soil test itself aims to understand the inorganic and organic minerals containment in the soil. Knowing this data, we can understand how great is that soil to grow the certain kind of crop. This kind of test also discover the microbial environment, fertility and pesticide residues in the soil. The soil testing uses the concept of analytical chemistry in its method.
6. Water Testing
Water is one of the vital part in the agriculture. The right water shall be chosen to perfectly grow your crops. Theres example of water which is not good for the crops like the type of water which is able to deposit lime on the fertile sole making that soil not proper to be cultivated. Analytical chemistry plays the great role in analyzing the water and showing all of water containment. It can define the right water for the crops. This study also gives us idea how to make changes to the water composition so that I can be fit with the crops.
