Solution may be defined as a homogeneous mixture of two or more pure substances, the relative ratio of which can be varied within certain limits. Solution of two substances is the most common type of solution and is termed as binary solution. The two components of a solution are :-
Solute: The substance which is dissolved in a solvent to produce a solution is called a solute. The solute particles in a solution are called dispersed particles.
Solvents: The liquid in which a substance is dissolved is called a solvent. A solvent is thus a dissolving agent. In a solution, the solvent is called the medium of dispersion.
Examples:
Sodium chloride, ammonium chloride, copper sulphate and sugar, which dissolve in water to form solutions, are called solutes, whereas water is called the solvent. Usually, the substance present in lesser amount in a solution is called the solute, and that present in greater amount is called the solvent.
‘Tincture of iodine’ is a solution of iodine and alcohol. Here, iodine is the solute and alcohol is the solvent.
