Question:

Write the net ionic equation for the reaction that occurs when aqueous solutions of hydroiodic acid and potassium hydroxide are mixed.

Potassium Iodide

Potassium iodide is an ionic compound industrially synthesized by the reaction between potassium hydroxide with iodine. It is used to treat iodine deficiency in the body.

Answer and Explanation: 1

Hydroiodic acid reacts with potassium hydroxide to form potassium iodide, and water formed as a by-product. The complete molecular equation is given as:

{eq}HI\left( {aq} \right) + KOH\left( {aq} \right) \to KI\left( {aq} \right) + {H_2}O\left( l \right) {/eq}

The complete ionic equation is given as;

{eq}{H^ + }\left( {aq} \right) + {I^ - }\left( {aq} \right) + {K^ + }\left( {aq} \right) + O{H^ - }\left( {aq} \right) \to {K^ + }\left( {aq} \right) + {I^ - }\left( {aq} \right) + {H_2}O\left( l \right) {/eq}

Crossing out the spectator ions to get the net ionic equation;

{eq}{H^ + }\left( {aq} \right) + O{H^ - }\left( {aq} \right) \to {H_2}O\left( l \right) {/eq}
