Concentration of a Solution Definition
Concentration of a solution is defined as the amount of solute dissolved in the solution. It is given by the ratio of the amount of solute to the amount of solution or solvent sometimes. However, we can express it in percentages, Parts per Million, and several other ways. The concentration of a solution can be expressed both qualitatively and quantitatively which we will see in the below topics. Before learning more about concentration let’s understand some of the general types of solution
Solution of Solid and Liquid
Solutions of solids and liquids involve the dissolution of a solid solute in a liquid solvent or a liquid solute in a liquid solvent. Examples include:
a. Solid in Liquid: Dissolving table salt (NaCl) in water.
b. Liquid in Liquid: Mixing ethanol and water to form a homogeneous solution.
Solution of Gas
Solutions of gases involve the dissolution of a gas in a liquid solvent or another gas. Examples include:
a. Gas in Liquid: Dissolving carbon dioxide (CO2) in water to form carbonated water.
b. Gas in Gas: Mixing different gases, such as oxygen and nitrogen, in the atmosphere to form a homogeneous mixture.
Concentration of a Solution
Concentration of Solution is a measure of the amount of solute that has been dissolved in the given amount of solvent. In simple words, it means determining how much of one substance is mixed with another substance. As Concentration is a frequently used term in chemistry and other relevant fields, although it is most commonly used in the context of solutions, where it refers to the quantity of solute dissolved in a solvent. Concentration can be expressed in both qualitative or quantitative (numerically) terms.
