उत्तर
Sodium nitrate can be prepared by the action of dil. HNO3 on sodium bicarbonate or sodium carbonate.
\[\ce{\underset{Sodium bicarbonate}{NaHCO3} + HNO3 {(dil.)} -> \underset{Sodium nitrate}{NaNO3} + CO2 + H2O}\]
\[\ce{\underset{Sodium carbonate}{Na2CO3} + 2HNO3 {(dil.)} -> \underset{Sodium nitrate}{2NaNO3} + CO2 + H2O}\]
