316729 Assertion :
\(\mathrm{BaCO}_{3}\) is more soluble in \(\mathrm{HNO}_{3}\) than in plain water.
Reason :
Carbonate is a weak base and reacts with the \(\mathrm{H}^{+}\)from the strong acid, causing the barium salt to dissociate.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
