Question

245. Action of dilute acids on metals

(c) $\mathrm{Cu}+{\mathrm{H}}_2{\mathrm{SO}}_4\to$

Answer 1

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

$\underset{\mathrm{Copper}}{\mathrm{Cu}\left(\mathrm{s}\right)}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{dil}\right)(\mathrm{aq}})\to \underset{\mathrm{Copper}\mathrm{Sulphate}}{{\mathrm{CuSO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}\mathrm{gas}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
