Acids and bases that are completely ionized when dissolved in water are called strong acids and strong bases. Strength of an acid or base can be decided by pH of the solution. The total pH scale ranges from 1 to 14, with 7 considered to be neutral. A pH less than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline.

a) Hydrochloric acid has pH 3.01 and that of acetic acid is 4.76. This makes hydrochloric acid a strong acid.

b) Sodium hydroxide has pH 13 and Calcium hydroxide is 12.20. This makes Sodium hydroxide a strong base.
