Question

Give the balanced equation for the following

Zinc sulphide and dilute Sulphuric acid

Answer 1

Part 1:- reaction of Zinc sulphide and dilute Sulphuric acid:-

1. When Zinc sulphide is reacted with dil. Sulphuric acid, Zinc sulphate and Hydrogen sulphide are formed as the product.
2. Hydrogen sulphide is the gas evolved here.
3. Balanced chemical equation $\underset{(\mathrm{Zinc}\mathrm{sulphide})}{\mathrm{ZnS}\left(\mathrm{s}\right)}+\underset{(\mathrm{Dil}.\mathrm{Sulphuric}\mathrm{acid})}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{(\mathrm{Zinc}\mathrm{sulphate})}{{\mathrm{ZnSO}}_4\left(\mathrm{aq}\right)}+\underset{(\mathrm{Hydrogen}\mathrm{sulphide})}{{\mathrm{H}}_2\mathrm{S}\left(\mathrm{g}\right)\left(\uparrow \right)}$

Therefore, the balanced chemical equation is $\underset{(\mathrm{Zinc}\mathrm{sulphide})}{\mathrm{ZnS}\left(\mathrm{s}\right)}+\underset{(\mathrm{Dil}.\mathrm{Sulphuric}\mathrm{acid})}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{(\mathrm{Zinc}\mathrm{sulphate})}{{\mathrm{ZnSO}}_4\left(\mathrm{aq}\right)}+\underset{(\mathrm{Hydrogen}\mathrm{sulphide})}{{\mathrm{H}}_2\mathrm{S}\left(\mathrm{g}\right)\left(\uparrow \right)}$
