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
पर्याय
(A) and (C)
(B) and (D)
(A) and (B)
(C) and (D)
उत्तर
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).
