Question

Zinc reacts with concentrated sulphuric acid to form zinc hydride and sulphide gas.

• A. True
• B. False

Answer 1

The correct option is B False

• Zinc reacts with concentrated sulphuric acid to form zinc sulphide and hydrogen gas will be evolved.

$\underset{\mathrm{Zinc}}{\mathrm{Zn}\left(\mathrm{s}\right)}+\mathrm{Con}.\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{\mathrm{Zinc}\mathrm{sulphate}}{{\mathrm{ZnSO}}_4\left(\mathrm{S}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)(\uparrow )}$

Thus, the given statement is false.
