Answer:
A solution, strictly speaking, is a mixture in which one substance, the solvent, is treated in a special way. Each of the other species comprising the mixture is then a solute. The solvent is denoted by A and the solute species by B, C, and so on. (Some chemists denote the solvent by subscript 1 and use 2 , 3 , and so on for solutes.) Although in principle a solution can be a gas mixture, in this section we will consider only liquid and solid solutions.
