General Preparation of Salts
Salts are generally ionic compounds formed by the reaction of an acid with a base. The preparation of these salts involves the treating of different metals and non-metals and their compounds with various acids, bases etc. However, some of them can be prepared by direct combination of the concerned elements or also by indirect routes.
Insoluble Salts by Precipitation
Precipitation is the reaction in which a solid is formed by the action between two or more fluids, e.g., calcium carbonate is precipitated when carbon dioxide is passed through limewater.
