Question

Dissociation of HCN is suppressed by the addition of HCl .

Answer 1

Explanation:

The addition of cyanide ions (CN–) will suppress the ionization of hydrogen cyanide (HCN) and shift its equilibrium to the left. The percent dissociation of the hydrogen cyanide will decrease, therefore decreasing the H+ ions and increasing the pH of the solution. “conjugate acid.”
