The following is a list of methods for the preparation of salts:
A — direct combination of two elements
B — reaction of a dilute acid with a metal
C — reaction of a dilute acid with an insoluble base
D — titration of a dilute acid with a solution of soluble base.
E — reaction of two solutions of salts to form a precipitate.
Choose from the list A to E, the best method of preparing the following salts by giving a suitable equation in each case:

Answer
- Anhydrous ferric chloride — A. (Direct combination of two elements)
2Fe + 3Cl2 ⟶ 2FeCl3 - Lead chloride — E. (Reaction of two solutions of salts to form a precipitate)
Pb(NO3)2 + 2NaCl ⟶ PbCl2 + 2NaNO3 - Sodium sulphate — D. (Titration of dilute acid with a solution of soluble base)
2NaOH + H2SO4 ⟶ Na2SO4 + 2H2O - Copper sulphate — C. (reaction of a dilute acid with an insoluble base)
Cu(OH)2 + H2SO4 ⟶ CuSO4 + 2H2O
