Answer» (A) Cr2+ is a reducing agent (B) Mn3+ is an oxidizing agent (C) Both Cr2+ and Mn3+ exhibit d4 electronic configuration (1) Cr2+ is a reducing agent because Cr3+ is more stable. (2) Mn3+ is an oxidizing agent because Mn2+ is more stable. (3) Cr2+ and Mn3+ exhibit d4 electronic configuration. |
