Concentrated sulfuric acid or phosphoric acid can also be used to catalyse the dehydration of an alcohol. The alcohol and concentrated acid are heated to about 170 °C. The concentrated acid does not change chemically during the reaction.

Write an equation showing the dehydration of ethanol using concentrated sulfuric acid.
