उत्तर
Dilute 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 CO2.
\[\ce{Na2CO3 + H2SO4 -> Na2SO4 + H2O + CO2 ↑}\]
