Question

Which of the following phenomena
occurs, when a small amount of acid
is added to water?
i. lonisation
ii. Neutralisation
iii. Dilution
iv. Salt formation
(1 Point)
(i) and (ii)
(i) and (iii)
(ii) and (iii)
(ii) and (iv)​

Answer 1

Answer:

(i) and (iii) : Ionization and Dilution

Explanation:

When a small amount of acid is added to water, a concentrated acid turns into dilute acid. This process is called dilution of acid. A dilute acid is also called an aqueous solution in which acid releases hydronium ions (H+) and undergoes ionization.

Answer 2

Answer:

(i) and (iii)

Explanation:

When acid is added in water, it gets diluted as the concentration of acid becomes less with respect to Concentration of water around it. (iii)

Sometimes in case of HCl and H2SO4, the acid gets dissociate to give H+ ion and an anion. These process can be called as ionisation (i)
