Question

Choose the correct option from given alternative:
When a small amount of acid is added to water, the phenomena which occur are:
(A) Dilution
(B) Neutralization
(C) Formation of H₃O⁺ ions
(D) Salt formation

Options

•  (A) and (C)

•  (B) and (D)

•  (A) and (B)

•  (C) and (D)

Answer 1

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 hydronium ion.

\[\ce{HCl +H2O -> H3O^+ + Cl^-}\]

Hence, the correct answer is an option  (A) and (C).
