Statement-1:White crystalline precipitate of silver sulphite dissolves if sulphite ions are added in excess.
Statement-2:Sulphite ions decolourise the pink colour of acidified `KMnO_4`

A

STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is correct explanation for STATEMENT-1

B

STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is not correct explanation for STATEMENT-2

C

STATEMENT-1 is true, STATEMENT-2 is false

D

STATEMENT-1 is false, STATEMENT-2 is true

Text Solution

Verified by Experts

The correct Answer is:
B

Statement-1 :`Ag_(2)SO_(3) darr +SO_(3)^(2-) to 2[Ag(SO_(3))]^(-)` (soluble complex)
Statement-2 :`5SO_(3)^(2-) + 2MNO_(4)^(-) ("pink")+6H^(+) to 2Mn^(2+) ("colourless") +5SO_(4)^(2-) +3H_(2)O`
