Question

Write word equations and then balanced equations for the reaction taking place when (a) Dilute sulfuric acid reacts with zinc granules

Answer 1

Reaction of metal with acid:

• When a metal reacts with the acid, it produces a metallic salt and hydrogen gas is liberated.
• The general chemical reaction can be depicted as:

$\mathrm{Metal}+\mathrm{Acid}\to \mathrm{Metallic}\mathrm{salt}+\mathrm{Hydrogen}$

Reaction of Dilute sulfuric acid with zinc granules:

• When Zinc$\left(\mathrm{Zn}\right)$ metal reacts with dilute sulfuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$, it produces Zinc sulfate$\left({\mathrm{ZnSO}}_4\right)$ and hydrogen gas$\left({\mathrm{H}}_2\right)$ is liberated.
• The word equation can be depicted as:

$\mathrm{Zinc}+\mathrm{dil}.\mathrm{Sulfuric}\mathrm{acid}\to \mathrm{Zinc}\mathrm{sulfate}+\mathrm{Hydrogen}$

• The chemical reaction can be depicted as:

$\mathrm{Zn}\left(\mathrm{s}\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)\to {\mathrm{ZnSO}}_4\left(\mathrm{s}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)$
