Assertion (A): Due to common ion effect, the solubility of `HgI_(2)` is expected to be less in an aqueous solution of `KI` than in water. But `HgI_(2)` dissolves in an aqueous solution of `KI` to form a clear solution. Reason (R) : `I^(Theta)` ions is highly polarisable.A. If both (A) and (R) are correc, and (R) is the correct explanation of (A).B. If both (A) and (R) are correct but (R) is not the correct explanation of (A).C. If (A) is correct, but (R) is incorrect.D. If (A) is incorrect, but (R) is correct. |

Answer» Correct Answer - B `HgI_(2) + KI rarr K_(2) [HgI_(4)] (A)` is true. `(R)` is also true since `I^(Theta)` ion is large sized and therefore is highly polarisable. But `(R)` is not the correct explanation of `(A)`, |
