Question

Write the net ionic equation for the reaction between hydrochloric acid and potassium cyanide. Do not include states such as (aq) or (s). Is the reaction reactant- or product-favored

Answer 1

Answer: $H^++CN^-\rightarrow HCN$, product favoured

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we do not include the spectator ions in the equations.

When hydrochloric acid react with potassium cyanide, then it gives potassium chloride and hydrocyanic acid as products.

The complete ionic equation will be:

$H^++Cl^-+K^++CN^-\rightarrow K^++Cl^-+HCN$

The net ionic equation will not contain spectator ions which are $K^+$ and $Cl^-$:

$H^++CN^-\rightarrow HCN$

The reaction is product favoured.
