Equivalent Weights Of Salts
To calculate the equivalent weight of a compound that is neither an acid nor a base, we need to know the charge of the cation or anion. The mass of the cation divided by the charge on it is called the equivalent mass of the cation, and the mass of the anion divided by the charge on it is called the equivalent mass of the anion. When we add equal masses of anions and cations, it gives us equal amounts of salt. For salts, the valence factor is the total amount of positive or negative charges provided by the 1 mol of salt.
Classification Of Inorganic Compounds
The Inorganic compounds that are classified as:
- Acids Acids are those compounds that dissolve in water and generate hydrogen ions or H+ Ions. The examples of acids include Hydrochloric acid, citric acid, sulphuric acid, vinegar, etc. One example of the acidic reaction is shown below-Hydrochloric acid + water H+ + Cl
- Bases A base is a type of substance or a compound that produces hydroxyl ions when kept in water. The bases like potassium hydroxide, calcium hydroxide, ammonia, sodium hydroxide produce OH- ions when dissolved in water. Potassium Hydroxide + H2O K+ + OH
- Salts As you might be familiar with the word Salt. The substances obtained as a result of the reaction between an acid and a base are called Salts. The table salt of sodium hydroxide is one of the typical examples of salts.
- Oxides The compounds which consist of one oxygen atom called Oxides.
What Is An Electrochemical Cell
An electrochemical cell is a piece of equipment that can create an electrical form of energy via chemical reactions. This produces energy to assist in various chemical reactions.
Class 12 Chemistry Electrochemistry notes further explain that this form of a cell can alter chemical energy into electrical. Moreover, electrical power to transform into chemical energy as per chapter 3 class 12 Chemistry notes is explained. The typical example of this form of a cell is the 1.5-volt battery used in day-to-day life. These batteries used to power tv remotes, clocks, toys, etc.
The best part of these cells is that they can generate current from reactions like a galvanic cell. Moreover, they can lead to chemical reactions when an electric current passes through. This becomes the base of electrolytic cells in class 12 Chemistry chapter 3 Electrochemistry notes.
This brings us to question what a Galvanic cell is? This has been explained in a detailed manner in class 12, chapter 3 Chemistry notes. Take a look!

Reactions In Aqueous Media
The two solids cannot react with each other in the solid phase, so they must be dissolved in the liquid. When solutes dissolve in a solvent, they coexist in a single phase called a solution. Several parameters are used to measure the strength of the solution. The strength of a solution denotes the amount of solute which is contained in the solution.
The parameters used to denote the strength of a solution are:
Mole dfraction \: moles of a component / Total moles of solution.
Mass\ : Mass of solute present in \ of solution.
\ : Mass of solute present in \ of solution
\ : Volume of solute/volume of solution
\ : Wt. of solute in \ of solution
ppm : \
1. Relation between molality Molarity , density of solution and molar mass of solute
\ : density in g/mL
\: molar mass in \
2. Relationship between molality and mole dfraction of the solute
Points to remember:
Molarity is the most common unit of measuring strength of solution.
The product of Molarity and Volume of the solution gives the number of moles of the solute, \
All the formulae of strength have an amount of solute. in the numerator.
All the formulae have an amount of solution in the denominator except for molality .
Classification Of Matter At Macroscopic Level
Matter can further be classified into following at bulk or macroscopic level:
Mixtures Pure Substances.
These can be further classified as shown below:
Mixtures : A mixture is a substance in which two or more substances are present in any ratio. Primarily, It is of two types: Heterogeneous and Homogeneous mixtures.
Homogeneous Mixture- Two substances are mixed to form a mixture such that there exist one single uniform phase i.e. composition of substances present is uniform. Sugar solution and air are thus, the examples of homogeneous mixtures.
Heterogeneous Mixtures- Two or more substances are mixed which result in non-uniform composition throughout the mixture. Some of the examples are suspensions, a mixture of two solids, suppose salt and sugar.
Note: Any distinct portion of matter that is uniform throughout in composition and properties is called a Phase.
Pure Substances:- A material containing only one type of particle is called a pure substance.
Note: In chemistry, forms of matter have constant chemical composition and chemical properties and they cannot be separated into components by physical methods.
Pure substances are further divided as given below:

What Do Chemists Do
Chemists work in a variety of fields, including research and development, quality control, manufacturing, environmental protection, consulting and law. They can work at universities, for the government or in private industry, according to the ACS.
Here are some examples of what chemists do:
Research and development
In academia, chemists performing research aim to further knowledge about a particular topic, and may not necessarily have a specific application in mind. Their results, however, can still be applied to relevant products and applications.
In industry, chemists in research and development use scientific knowledge to develop or improve a specific product or process. For example, food chemists improve the quality, safety, storage and taste of food pharmaceutical chemists develop and analyze the quality of drugs and other medical formulations and agricultural chemists develop fertilizers, insecticides and herbicides necessary for large-scale crop production.
Sometimes, research and development may not involve bettering the product itself, but rather the manufacturing process involved in making that product. Chemical engineers and process engineers devise new ways to make the manufacturing of their products easier and more cost effective, such as increasing the speed and/or yield of a product for a given budget.
How Do You Make Na2co3 Solution
Weigh the calculated amount of sodium carbonate on the scale. Pour distilled water20 to 30 mL less than the final volumeinto the beaker, then add sodium carbonate. In our example, start with 270 to 280 mL of water. Mix the solution with a spoon or gently swirl the beaker until the salt dissolves completely.

Origin Of Equivalent Concept
The equivalent weight of an element was originally defined as the weight of the element combined with 1 grams of hydrogen. Subsequently, the definition was modified as follows: the equivalent weight of an element is the weight of the element combined with 8 grams of oxygen. Note: Same element can have multiple equivalent weights depending upon the charge on it. e.g. \ and \
Classification Of Carbon Atoms
Carbons have a special terminology to describe how many other carbons they are attached to. This allows for an easy description of branching in alkanes. Also, we will find that the number of carbons attached to a given atom will have subtle effects on its chemistry.
- Primary carbons attached to one other C atom.
- Secondary carbons are attached to two other Cs.
- Tertiary carbons are attached to three other Cs.
- Quaternary carbons are attached to four C’s.
The figure below use the group “R” to represent an alkyl group of unspecified length. R typically used to represent alkyl groups but an also represent a part of a molecule which is either unspecified or not germane to the discussion.
This terminology will be used repeatedly in organic chemistry to describe the number of carbons attached to a specific atom, however, the atom will not always a carbon.
Please indicate the the number of 1o, 2o, 3o, and 4o carbons in the following molecule:
- The molecule has six Primary carbons .
- The molecule has one Secondary carbon .
- The molecule has one Tertiary carbon .
- The molecule has one Quaternary carbon
Hydrogen atoms are also classified in this manner. A hydrogen atom attached to a primary carbon atom is called a primary hydrogen ect.
Please indicate the the number of 1o, 2o, and 3o, hydrogens are in the following molecule:
- The molecule has fifteen Primary hydrogens.
- The molecule has two Secondary hydrogens.
- The molecule has one Tertiary hydrogen.

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.
Law Of Chemical Combination
7.1 Law of Conservation of Mass
In a chemical reaction the mass of reactants consumed and mass of the products formed is the same, that is mass is conserved. This is a direct consequence of the law of conservation of atoms. This law was given by Antoine Lavoisier in \.
7.2 Law of Constant / Definite Proportions
The law of definite proportions states that the mass proportions of the elements in a composite sample are always the same. It was given by a French chemist, Joseph Proust.
7.3 Law of Multiple Proportions
The law of multiple proportions states that when two elements are combined to form more than one compound, the weight of one element is proportional to the fixed weight of the other element as a whole number. This law was proposed by Dalton in \.
7.4 Law of Reciprocal Proportions
The law states that if two different elements are combined with the fixed mass of the third element, their combined mass ratio is the same, or a simple multiple of their combined mass. This Law was proposed by Richter in \ .
7.5 Gay Lussacs Law of Gaseous Volumes
The law developed by Gay Lussac in 1808 establishes that “the relationship between the volume of a gaseous reactant and a product can be represented by a simple whole number.”
7.6 Avogadro Law
In \ , Avogadro proposed that equal volumes of gases at the same temperature and pressure should contain an equal number of molecules.

What Is Inorganic Chemistry
The word organic refers to the compounds which contain the carbon atoms in it. So the branch of chemistry that deals with the study of compounds, which does not consist of carbon-hydrogen atoms in it, is called Inorganic Chemistry. In simple words, it is opposite to that of Organic Chemistry. The substances which do not have carbon-hydrogen bonding are the metals, salts, chemical substances, etc.
On this planet, there are known to exist about 100,000 number of Inorganic compounds. Inorganic chemistry studies the behaviour of these compounds along with their properties, their physical and chemical characteristics too. The elements of the periodic table except for carbon and hydrogen, come in the lists of Inorganic compounds.
Many of the elements are technologically important: titanium, iron, nickel and copper, for example, are used structurally and electrically. Second, the transition metals form several useful alloys, with each other and with other metallic elements.
