Assertion: Sulphate is estimated as

\mathrm{BaSO}_4

and not as

\mathrm{MgSO}_4

.
Reason: Ionic radius of

\mathrm{Mg}^{2+}

is smaller than

\mathrm{Ba}^{2+}

View answer and explanation

Correct option: D

Both Assertion and Reason are correct but Reason is not correct explanation of Assertion

Option D (Both Assertion and Reason are correct but Reason is not correct explanation of Assertion) is correct because while both statements are true, the smaller ionic radius of Mg2+ doesn't directly explain why sulfate is estimated as BaSO4.
