Acids and bases and elimination reactions


Many industrial processes consist of equilibrium reactions.

We all know that if a simple acid and base are mixed, the result is the formation of water as an ionic reaction:

If the water is removed by evaporation, then salt is left. For example, if one mixes solutions of sodium hydroxide and hydrochloric acid, the hydrogen ions and hydroxide ions form water, leaving free sodium ions and chloride ions in solution. After evaporation, these crystallise to form sodium chloride:

Certain organic compounds exhibit analogous reactions, in particular the elimination of water in the elimination reaction between an amine and an organic acid:
