(a) It decolourises KMnO₄
Explanation:
Mohr's Salt is a double salt and it reacts with KMnO4 according to the following reaction:
KMnO4 + Fe2+ ----> Fe3+ + Mn2+
Hence KMnO4 will be decolourised. So statement A is correct.
Statements B, C and D are not correct in case of Mohr's salt.
Option A is the answer.
