Question

Write a net ionic equation to show that hydrocyanic acid , hcn , behaves as an acid in water.

Answer 1

Answer: The net ionic equation is given below.

Explanation:

Hydrocyanic acid (HCN) is a weak acid which means that it does not get completely dissociated when dissolved in water.

The ionization equation for HCN follows:

$HCN+H_2O\rightarrow H_3O^++CN^-$

There are no spectator ions in the equation (ions which are present on both the sides of the reaction). So, the above reaction is the net ionic equation.

Hence, the net ionic equation is given below.

Answer 2

HCN+H20<---->H30⁺ +CN⁻
