Question

What do you mean by a concentration of a solution ? Mention two ways of expressing the concentration of a solution.

Answer 1

A solution is a sort of homogenous combination made up of two or more components in chemistry. A solute is a material that is dissolved in another substance, known as a solvent, in such a combination. The mixing of a solution takes place at a scale where the effects of chemical polarity are present, resulting in solvation-specific interactions. When the solvent makes up the majority of the combination, as is often the case, the solution takes on the state of the solvent.

Complete answer:
Concentration is defined as the abundance of an ingredient divided by the total volume of a mixture in chemistry. Mass concentration, molar concentration, number concentration, and volume concentration are all examples of mathematical descriptions. A concentration can be any chemical combination, although solutes and solvents in solutions are the most common. Normal concentration and osmotic concentration are two types of molar (amount) concentration.
The concentration of a solution refers to the amount of solute in the solvent. The amount of solute in a solvent is defined as concentration of solution in chemistry. A concentrated solution contains more solute than a standard solution. When a solution has more solvent, it is referred to as a dilute solution. Let's move on to the numerous techniques of expressing concentration now that you've grasped the notion of what is concentration of solution.
The quantity of solute contained in one litre of solution is known as the concentration of the solution. The two methods for expressing a solution's concentration are listed below. Let's say we have a solution with component A as the solute and component B as the solvent.
(i) Mass % of solute A (W/W):
$\text{Mass of solute A }\\!\\!\div\\!\\!\text{ }\\!\\!~\\!\\!\text{ Total mass of solution x 100}$
(ii) Volume percentage of solution (V/V):
$\text{Mass of solute A }\\!\\!\div\\!\\!\text{ Total volume of solution x 100}$ .

Note:
There are two components to an aqueous solution: the solute and the solvent. These are the two most important words to understand when it comes to solution concentration. The quantity of solute in the solution must constantly be kept in mind.
