Aqueous Equilibrium and Precipitation Reaction- Suppression of Ionization of Ammonium Hydroxide II

Suppression of Ionization of Ammonium Hydroxide II

 

Description: A magnesium chloride solution is split between two beakers, and a solid ammonium chloride is added to one. Subsequent addition of aqueous ammonia to the beakers produces a precipitate of magnesium hydroxide in only one beaker.
