Question

Write the net ionic equation for acid base hydrolysis equilibrium that is established when potassium cynaide is dissolved in water

Answer 1

The net ionic equation is the representation of the elements in ionic form. The acid-base hydrolysis is given as, CN⁻(aq) + H₂O (l) ⇄ HCN(aq) + OH⁻(aq).

What are ionic equations?

Ionic equations are a representation of the ions that are included in a reaction to form the product. It excludes the spectator ions as they are unable to get dissolved.

Potassium cyanide reacts with water to produce a weak acid and a strong base. The reaction is given as,

KCN(aq) + H₂O(l) ⇄ KOH(aq) + HCN(aq)

Here, KOH is a strong base and HCN is a weak acid. The net ionic equation of the basic solution will be given as,

CN⁻(aq) + H₂O (l) ⇄ HCN(aq) + OH⁻(aq).

Therefore, KOH being a spectator ion will not be included in the net ionic equation.
