State how would you prepare copper (II) oxide from
copper sulphate
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.
Choosing the correct words given in brackets, complete the sentence given below: Sodium sulphate from sodium carbonate.
The preparation of lead sulphate from lead carbonate is a two step process (lead sulphate cannot be prepared by adding dilute sulphuric acid to lead carbonate)
What is the first step that is required to prepare lead sulphate from lead carbonate?
