(i) Formation of a basic salt — A basic salt is formed by partial replacement of hydroxyl radicals of a diacidic or triacidic base with an acid radical.
(ii) Components of a basic salt — A basic salt contains a cation [metallic], a hydroxyl ion [of a base] and an anion [of an acid].
For example — Basic copper nitrate Cu[OH]NO3 , basic copper chloride Cu[OH]Cl
Acid, normal or basic salt —
(i) bleaching powder — Normal salt (Mixed salt)
(ii) potassium mercuric iodide — Normal salt (Complex salt)
(iii) sodium sulphite — Normal salt
(iv) sodium hydrogen sulphite — Acid salt
(v) sodium silver cyanide — Normal salt (Complex salt)
(vi) basic lead nitrate — Basic salt
(vii) potassium zincate — Normal salt
(viii) alum — Normal salt (Double salt)
(ix) calcium bicarbonate — Acid salt
(x) basic copper chloride — Basic salt
(xi) trisodium phosphate — Normal salt

State which solution is transferred to the evaporating dish and evaporated to point of crystallization for obtaining the salt.5. State why titration is not conducted for the preparation of copper [II] sulphate crystals by neutralization.
