Dilution is the process of making a concentrated solution less concentrated. There are a variety of reasons why one might want to perform a dilution. For example, biochemists dilute solutions from their concentrated form to create new solutions for use in their experiments. As a more casual type of dilution, bartenders often dilute hard liquor with a soft drink or juice to make a cocktail more palatable. For diluting solutions in lab experiments, the formal formula for calculating a dilution is C1V1 = C2V2, where C1 and C2 represent the concentrations of the initial and final solutions, respectively, and V1 and V2 represent their volumes.

Definitions And Examples Of How To Calculate Wt% Molarity And How To Prepare Dilutions

A solution is in chemistry defined as:

  • A homogeneous mixture composed of two or more substances.
  • The process by which a gas, liquid, or solid is dispersed homogeneously in a gas, liquid, or solid without chemical change.

The substance in which another substance dissolves is called the solvent, while the dissolved substance is called the solute.

The solution assumes the characteristics of the solvent when the solvent is the larger fraction of the mixture, as is commonly the case. From this, the solute is usually the component of a solution present in the lesser amount.

Solubility is the ability of a solute to dissolve in a solvent. The solubility of a substance in another is not unlimited, and how much solute you can solve in a solvent varies a lot. Tabulated values of solubility refer to max grams of solute in a given amount of the solvent.

  • solubility is dependent on temperature. In general, but not without expectations, solubility increases with temperature
  • smaller particles dissolves faster than larger particles
  • a solid dissolves faster if the mixture is stirred or shaken

A saturated solution contains the maximum amount of solute in the solvent, given by the solubility.

Examples of common solutions:

  • tea with sugar – a solution of sugar in hot water
  • seawater – a solution of salt in water

The concentration of a solute in a solution is can be given as

  • the mass of solute expressed as a percentage of the mass of the whole solution, which is the mass% or wt%

    What Is A Solution

    Before you can make a simple dilution, it is a good idea to understand the terminology since some of the words sound similar. A solution is a liquid mixture where a smaller amount of a substance called a solute is mixed into a larger amount of a solvent like water. A solution with a great deal of solute is concentrated while a solution with a smaller amount of solute is dilute.

    Sometimes you must use a concentrated solution and add more solvent to create a simple dilution. To visualize, household bleach is a solution that contains sodium hypochlorite and water. This solution is much too concentrated to use directly from the bottle, so you add water in a spray bottle, bowl or the basin of the washing machine to create a simple dilution of bleach.

    Starting With Final Volume

    If your simple dilution requires a more precise final volume, you should first determine how many total parts your final solution will contain. In a 1:4 ratio, there are five total parts . You can then divide the end volume by the total parts to determine the volume of one part. For example, if you know you need 40 ounces of that 1:4 bleach dilution, you can divide 40 ounces by 5 parts and find that each part is 8 ounces. Using simple subtraction, you know you will need 8 ounces of bleach and 32 ounces of water.

    Whether you are making simple dilutions to use in your home or in a laboratory, understanding dilution ratios is an invaluable skill.

    Chemistry Is Everywhere: Preparing Iv Solutions

    In a hospital emergency room, a physician orders an intravenous delivery of 100 mL of 0.5% KCl for a patient suffering from hypokalemia . Does an aide run to a supply cabinet and take out an IV bag containing this concentration of KCl?

    Not likely. It is more probable that the aide must make the proper solution from an IV bag of sterile solution and a more concentrated, sterile solution, called a stock solution, of KCl. The aide is expected to use a syringe to draw up some stock solution and inject it into the waiting IV bag and dilute it to the proper concentration. Thus the aide must perform a dilution calculation.

    If the stock solution is 10.0% KCl and the final volume and concentration need to be 100 mL and 0.50%, respectively, then it is an easy calculation to determine how much stock solution to use:

    V1 = V1 = 5 mL

    Of course, the addition of the stock solution affects the total volume of the diluted solution, but the final concentration is likely close enough even for medical purposes.

    Medical and pharmaceutical personnel are constantly dealing with dosages that require concentration measurements and dilutions. It is an important responsibility: calculating the wrong dose can be useless, harmful, or even fatal!

    The first option works best when you know precisely how much solute or concentrated solution you have or want to use. For example, to make a simple dilution using a 1:4 dilution ratio with a 10 mL sample in a laboratory, you know that one part equals your 10 mL sample. If you multiply that one part by four parts, you know that you should add 40 mL of water to your sample, resulting in a 1:4 ratio .

    This strategy also works well for making a simple dilution when your end volume doesnt really matter. For example, if you are making a dilution of bleach for household cleaning, you can quickly mix one part bleach with four parts water to make your 1:4 dilution ratio.

    What Is A Dilute Solution

    A dilute solution has a low concentration of the solute compared to the solvent. The opposite of a dilute solution is a concentrated solution, which has high levels of solute in the mixture.

    To achieve a dilute solution, more solvent is simply added without adding any more solute into the original mixture. The solution is then stirred to mix the two ingredients thoroughly. This ensures that all parts of the mixture have the same composition. The chemicals that can be diluted are gases, vapors and liquids. Solutions are diluted and can be monitored to attain a desired level of concentration.

    What Is A Dilution Ratio

    When you make a simple dilution that contains one part concentrated solution and four parts water as a solvent, you are using a 1:4 dilution ratio. This means there are five total parts in the diluted solution you have in the end. There are two simple ways to figure out how much solute and solvent you will need: measuring parts based on the amount of solute you have or measuring parts using your intended final volume.

      Why Dilution Is Important

      Dilution of solutions helps us in many ways. During titration, solutions are diluted so there is a larger volume of solution available. This allows the students to conduct multiple titrations without the fear of running out the solution. Solutions are also diluted because acids, at higher concentrations, are very corrosive to the skin and can have permanent effects. So, for safety reasons as well, solutions are diluted.

      Question

      25 cm3of KmnO4 at the concentration of 0.1 mol/dm3 is pipetted and added to the beaker. That 25 cm3 is diluted with water till the volume in the beaker is 100 cm3. Find the concentration of KMnO4 in the beaker.

      Solution

      The first statement indicates that KmnO4 had the original concentration of 0.1 mol/dm3. This can also be written as per 1 dm3 of water, there are 0.1 moles of KMnO4. By using the

      ratio method, we can find out the number of moles in the 25 cm3sample that was pipetted out.

      Moles

      X = /1000

      X = 0.0025 moles

      0.0025 moles of KMnOwere taken out when 25 cm3of the solution was pipetted out.

      Then, the 25 cm3was made into 100 cm3by adding water. As we discussed earlier, adding water only makes the concentration and the volume change. The moles and the mass of the solute remain as is. So, the 100 cm3will have the same number of moles as the 25 cm3 that was pipetted out. Now, we know that 100 cm3will have 0.0025 moles of KMnO4 in it, we can calculate its concentration using the ratio method.

      Moles
      x1000

      X = /100
