Write a chemical equation for NH4+(aq) showing how it is an acid or a base according to the Arrhenius definition.

Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation:

According to this theory, an acid is a substance that is a proton donor when the substance is dissolved in water.

The base is the one that gives OH- ions when dissolved in water.

KOH(aq) is a base.

Because it releases OH- ions when dissolved in water.

$KOH(aq)->K^+(aq)+OH^-(aq)$

The ammonium ion is an acid.

It can donate a proton when dissolved in water.

$NH_4^+(aq)->NH_3(aq)+H^+(aq)$
