Question

202(d) Give two examples of strong bases.

Answer 1

• The bases that dissociate completely into their constituent ions in an aqueous solution are called strong bases.
• They undergo 100% dissociation in an aqueous solution.
• The examples of strong bases are:

(i) Sodium hydroxide (NaOH) is a strong base as it dissociates completely and generates sodium (Na⁺) and hydroxide (OH^-) ions when dissolved in water.

(ii) Potassium hydroxide (KOH) is a strong base as it dissociates completely and generates potassium (K+) and hydroxide (OH^-) ions when dissolved in water.
