Question

Complete the reaction:-

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

Answer 1

• When a metal reacts with acids, salt is formed and hydrogen gas is liberated.
• The general reaction is:$\mathrm{Metal}+\mathrm{Acid}\to \mathrm{Salt}+\mathrm{Hydrogen}\mathrm{gas}$
• Zinc$\left(\mathrm{Zn}\right)$ liberates hydrogen gas$\left({\mathrm{H}}_2\right)$ at room temperature when it comes in contact with dilute Sulphuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$.
• The complete reaction is: $\underset{\mathrm{Zinc}}{\mathrm{Zn}}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{\mathrm{dil}.{\mathrm{H}}_2{\mathrm{SO}}_4}\to \underset{\mathrm{Zinc}\mathrm{sulphate}}{{\mathrm{ZnSO}}_4}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2}$
