Making magnesium carbonate: the formation of an insoluble salt in water

Description

When solutions of two soluble salts are mixed, a solid may form. The solid is called a precipitate, and the reaction is called a precipitation reaction. In this experiment insoluble magnesium carbonate is precipitated which can be filtered, dried and collected.
