Choose the statement below that is TRUE.

Leni [432]

Answer: Option (a) is the correct answer.

Explanation:

A weak acid is defined as an acid that dissociates partially when dissolve in water or a polar solvent.

For example, acetic acid is a weak acid and when dissolved in water it dissociates partly into ions as follows.

$CH_{3}COOH(aq) \rightleftharpoons CH_{3}COO^{-}(aq) + H^{+}(aq)$

And, a strong acid is defined as an acid which when dissolved in water dissociates completely into ions.

For example, HCl is a strong acid and when dissolved in water it dissociates completely.

$HCl \rightarrow H^{+} + Cl^{-}$

Thus, we can conclude that the statement a weak acid solution consists of mostly non-ionized acid molecules, is true.
