Assertion : BaCO_3 is more soluble in HNO_3 than in plain water....

Assertion : BaCO3\mathrm{BaCO}_3 is more soluble in HNO3\mathrm{HNO}_3 than in plain water. Reason : Carbonate is a weak base and reacts with the H+\mathrm{H}^{+}from the strong acid, causing the barium salt to dissociate.

Options

  1. AIf both assertion and reason are true and the reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true and the reason is not the correct explanation of the assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and the reason is the correct explanation of the assertion

Step-by-step solution

BaCO3+2HNO3→Ba(NO3)2+H2O+CO2\mathrm{BaCO}_3+2 \mathrm{HNO}_3 \rightarrow \mathrm{Ba}\left(\mathrm{NO}_3\right)_2+\mathrm{H}_2 \mathrm{O}+\mathrm{CO}_2.
