For each of the salt: A, B, C and D, suggest a suitable method for its preparation.

(a) A is a sodium salt.

(b) B is an insoluble salt.

(c) C is a soluble salt of copper.

(d) D is a soluble salt of zinc.

Solution

(a) A is sodium salt: It is prepared by neutralization of a base with acids.
(b) B is an insoluble salt: An insoluble salt is obtained from another insoluble salt by double decomposition. The insoluble salt is first converted into a soluble salt which is then used to prepare the desired salt.
(c) C is a soluble salt of copper: The soluble salt of copper can be prepared by the decomposition of carbonates by acids.
(d) D is a soluble salt of Zinc: The soluble salt of Zinc can be prepared by decomposition of chlorides by conc. $H_{2} S O_{4} .$
