Question

The following is the list of methods for the preparation of salts.​

(A) Direct combination of two elements.​

(B) reaction of dilute acid with a metal.​

(C) Reaction of dilute acid with an insoluble base.​

(D) Titration of dilute acid with a solution of soluble base.​

(E) Reaction of two solutions of salts to form a precipitate.​

Choose from the above list A to E, the best method of preparing the following salts by giving a suitable equation in each case:​

4. Copper sulphate​

Answer 1

(C) Reaction of dilute acid with an insoluble base.
Copper sulphate can be prepared by the reaction of a dilute acid with an insoluble base. It is a neutralization reaction
The chemical equation for the above reaction can be given as,
$Cu(OH{)}_2+H_2{SO}_4\to {CuSO}_4+2H_{2}O$
