# What is the complete ionic equation for the reaction of hydrochloric acid with potassium hydroxide?

Dec 5, 2016

${H}^{+} + C {l}^{-} + {K}^{+} + O {H}^{-} = {K}^{+} C {l}^{-} + {H}_{2} O$

#### Explanation:

Hydrochloric acid is HCl. This is an ionic substance so in water it breaks apart into ions ${H}^{+} + C {l}_{-}$

Potassium Hydroxide is also an ionic substance it also breaks apart in water into ions ${K}^{+} + O {H}^{-}$

So the complete ionic equation for the reaction is

${H}^{+} + C {l}^{-} + {K}^{+} + O {H}^{-} = {K}^{+} + C {l}^{-} + {H}_{2} O$

The Hydrogen ion and the Hydroxide ions combine to form water.

The net ionic equation is

${H}^{+} + O {H}^{-} = {H}_{2} O$

This is because the $C {l}^{-} + {K}^{+}$ ions do not undergo any changes therefore are not part of the net ionic equation.
