is ammonia base or acid

Ammonia (NH3) is a weak base. A base is a substance that can accept a proton (H+) from an acid to form a new substance. In the case of ammonia, it can accept a proton from an acid to form the ammonium ion (NH4+).The basicity of ammonia comes from its ability to form hydroxide ions (OH-) in water. When ammonia is dissolved in water, it reacts with water molecules to form ammonium ions and hydroxide ions:NH3 + H2O → NH4+ + OH-

The hydroxide ions give the solution a basic character, making it more alkaline. The pH of a solution containing ammonia depends on the concentration of ammonia and the temperature of the solution.Overall, ammonia is a weak base compared to strong bases like sodium hydroxide (NaOH) or potassium hydroxide (KOH), which can completely dissociate into hydroxide ions in water.
