Question

Match the products formed if the following reactants combine with dilute sulphuric acid.

• A. ${\mathrm{Na}}_2{\mathrm{SO}}_4+H_{2}O$
• B. ${\mathrm{Na}}_2{\mathrm{SO}}_4+H_{2}O+{\mathrm{CO}}_2$
• C. ${\mathrm{Na}}_2{\mathrm{SO}}_4+{\mathrm{SO}}_2+H_{2}O$
• D. ${\mathrm{Na}}_2{\mathrm{SO}}_4+H_{2}S$

Answer 1

The general reactions of dilute sulphuric acid with metal compounds are:

Acid + Base/Metal oxide	Salt + Water
Acid + Metal Carbonate/Bicarbonate	Salt + Water + Carbon dioxide
Acid + Metal Sulphite/Bisulphite	Salt + Water + Sulphur dioxide
Acid + Metal Sulphide	Salt + Hydrogen Sulphide
