Question

What is always true of a weak acid ?

Answer 1

Answer: D. it only partially dissociates in solution.

Explanation:

Strong acid is defined as the acid which completely dissociates when dissolved in water. They have low pH. These releases $H^+$ ions in their aqueous states.

$HNO_3(aq.)\rightarrow H^+(aq.)+NO_3^-(aq.)$

Weak acid is defined as the acid which does not completely dissociates when dissolved in water. They have high pH. These releases $H^+$ ions in their aqueous states.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

Thus the correct option is it only partially dissociates in solution.
