Question
Give two balanced reactions of the type to show the following property of sulphuric acid:
Acidic nature.
Solution
- Dilute \[\ce{H2SO4}\] reacts with basic oxides to form salt and water.
\[\ce{\underset{hydroxide}{\underset{Sodium}{2NaOH_{(aq)}}} + H2SO4_{(aq)} -> \underset{Sulphate}{\underset{Sodium}{Na2SO4_{(aq)}}} + 2H2O_{(l)}}\] - \[\ce{CuO + H2SO4 -> CuSO4 + H2O}\]
- It reacts with carbonate to produce \[\ce{CO2}\].
\[\ce{Na2CO3 + H2SO4 -> Na2SO4 + H2O + CO2 ↑}\]
