In this practical, students react alkaline ammonia with sulfuric acid to form the soluble salt ammonium sulfate. Includes kit list and safety instructions.

An acid and an alkali react to form a soluble salt in solution. In this experiment, students produce ammonium sulfate from the reaction between ammonia and sulfuric acid. They can then recover this salt by crystallisation.
