What do you mean by aqueous solutions and non aqueous solutions ?

Solutions in which water is the solvent are called aqueous solutions. For example, when sugar is dissolved in water, the solution obtained is called an aqueous solution of sugar.

The solutions obtained by dissolving a solute in any solvent other than water are called non aqueous solutions (non acqueous means without water). For example, if a solute is dissolved in any solvent such as benzene, alcohol, ether, carbon, disulphide, carbon tetrachloride, acetone, etc., the solution obtained is called a non aqueous solution.

Some commonly used non aqueous solutions are,

(a) Solution of sulphur in carbon disulphide

(b) Solution of iodine in carbon tetrachloride

(c) Solution of iodine in alcohol (tincture of iodine).
