Question

When a small amount of acid is added to water, the phenomena which occur are:

1. Dilution
2. Neutralisation
3. Formation of H₃O⁺ ions
4. Salt formation

Options

•  (A) and (C)

•  (B) and (D)

•  (A) and (B)

•  (C) and (D)

Answer 1

 (A) and (C)

Explanation:

The addition of acid to water is known as the process of dilution of acid; in this, the acid molecule loses H+ ions in the solution to form a hydronium ion.
