Question

245. The action of dilute acids on metals

(a)$\mathrm{Zn}+{\mathrm{H}}_2{\mathrm{SO}}_4\to$

Answer 1

• When Zinc reacts with dilute Sulphuric acid, it will form Zinc sulfate and Hydrogen gas.
• Zinc being more reactive than Hydrogen, it will displace Hydrogen from Sulphuric acid.
• The chemical equation for the given reaction is as follows:

$\underset{\mathrm{Zinc}}{\mathrm{Zn}\left(\mathrm{s}\right)}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{\mathrm{Zinc}\mathrm{Sulpahte}}{{\mathrm{ZnSO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}\mathrm{gas}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
