Question

what is the method of preparation of an insoluble salt

Answer 1

Preparing an insoluble salt. Two soluble metal salts react with each other to form one soluble salt and one insoluble salt . Lead nitrate solutionand sodium chloride solution react to produce solid lead chloride , leaving soluble sodium nitrate in solution. The lead chloride can be recovered byfiltration.

Answer 2

An insoluble salt can be prepared by a precipitation method through a double decomposition reaction. In this method two aqueous solutions of two different soluble salts are mixed together to form the insoluble salt. The insoluble salt is formed as a precipitate and can be obtained by filtration. The method of preparation of insoluble salt is known as the precipitation method.
