Give one equation to show the following property of sulphuric acid:
Acidic nature
उत्तर
Acidic nature of sulphuric acid: It acts as a strong dibasic acid.
\[\ce{H2SO4 -> 2Hi+ + SO^{2-}_{4}}\]
It reacts with metals, metal oxides, metal hydroxides, and carbonates to form metallic sulphates and hydrogen at ordinary temperature.
\[\ce{Mg + H2SO4 -> MgSO4 + H2\uparrow}\]
\[\ce{CuO + H2SO4 -> CuSO4 + H2O}\]
\[\ce{2NaOH + H2SO4 -> Na2SO4 + 2H2O}\]
\[\ce{ZnCO3 + H2SO4 -> ZnSO4 + H2O + CO2\uparrow }\]
