Question

What is always true of a weak acid ?

Answer 1

the answer is d per me

Answer 2

Answer: D. it only partially dissociates in solution.

Step-by-step 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.
