Question

Choosing only substances from the list given in the box below, write equations for the reactions which you would use in the laboratory to obtain: Sodium sulphate

Dilute sulphuric acid	Copper	Copper carbonate
	Iron	Sodium carbonate
	Sodium
	Zinc

Choosing the substances from the list given below, write balanced chemical equations for the reactions which would be used in the laboratory to obtain the following salts:

Dilute sulphuric acid	Copper	Copper (II) carbonate
	Iron	Sodium carbonate
	Sodium	Sodium chloride
		Zinc nitrate

Sodium sulphate

Answer 1

Sodium sulphate is obtained by the action of dilute sulphuric acid and sodium carbonate.

\[\ce{Na2CO3 + H2SO4_{(dil.)}-> Na2SO4 + H2O + CO2_{(g)}}\]
