Question:

Write the net ionic equation for the reaction that occurs when aqueous solutions of sodium hydroxide and hydrocyanic acid are combined.

Acids-Base Reactions:

Acids and bases can react together via a proton transfer reaction in which the the acid donates a proton to the base which accepts it. This reaction results in the formation of the conjugate acid-base pairs of the acid and base.

Answer and Explanation: 1

When weak acids like hydrocyanic acid are combined with strong bases like sodium hydroxide, the reaction will involve the deprotonation of the acid by the hydroxide ion from the base. This reaction results in the formation of the conjugate base of the acid and water. The net ionic equation for this reaction is shown below:

{eq}OH^-_{(aq)} + HCN_{(aq)} \to CN^-_{(aq)} + H_2O_{(l)} {/eq}
