From the list of the substances given, name the substances which you would use to prepare each of the following salts:
List of substances: copper, lead, sodium, zinc, copper oxide, lead carbonate, sodium carbonate solution, dilute hydrochloric acid, dilute nitric acid and dilute sulphuric acid.
Salts: (a) zinc sulphate (b) copper sulphate (c) sodium sulphate (d) lead sulphate.
(a) Zinc sulphate is prepared by displacement reaction between zinc and dilute sulphuric acid.
(b) Copper sulphate is prepared by the neutralisation reaction of copper oxide with dilute sulphuric acid.
(c) Sodium sulphate is prepared by the neutralisation of soluble base i.e. sodium carbonate with dilute sulphuric acid.
(d) Lead sulphate: Preparation of lead sulphate from lead carbonate involves the following steps:
Step 1: Insoluble lead carbonate first reacts with dilute nitric acid to form soluble lead nitrate.
Step 2: Dilute sulphuric acid is added to lead nitrate to form lead sulphate and nitric acid.
