Assertion :- `Cr^(+2)` is a reducing agent and `Mn^(+3)` is oxidising agent.
Reason :- `Mn^(+3)` has `d^(5)` configuration.

Assertion : Cr^(2+) is reducing and Mn^(3+) is oxidising. Reason : Cr^(2+) and Mn^(3+) have d^4 configuration.

Assertion : Cr^(2+) is reducing and Mn^(3+) is oxidising. Reason : Cr^(2+) and Mn^(3+) have d^4 configuration.

Which of the following statement are correct about Cr^(2+) (Z = 24) and Mn^(3+) (Z = 25) ? (i) Cr^(2+) is a reducing agent (ii) Mn^(3+) is an oxidizing agent (iii) Both Cr^(2+) and Mn^(3+) exhibit d^(4) configuration (iv) When Cr^(2+) is used as a reducing agent, the chromium ion attains d^(5) electronic configuration

Which of the following statement are correct about Cr^(2+) (Z = 24) and Mn^(3+) (Z = 25) ? (i) Cr^(2+) is a reducing agent (ii) Mn^(3+) is an oxidizing agent (iii) Both Cr^(2+) and Mn^(3+) exhibit d^(4) configuration (iv) When Cr^(2+) is used as a reducing agent, the chromium ion attains d^(5) electronic configuration

The ion Cr^(2+) is redusing agent while that of Mn^(3+) is an oxidising agent though both have 3d^(4) configuration. This is because

Assertion : HNO_(2) can act both as a reducing agent and an oxidising agent. Reason : In HNO_(2) , oxidation state of nitrogen is +3 which can change from -3 to +5.

Four statements for Cr and Mn are given below: (i) Cr^(2+) and Mn^(3+) have the same electronic configuration. (ii) Cr^(2+) is a reducing agent while Mn^(3+) is an oxidising agent. (iii) Cr^(3+) is an oxidizing agent while Mn^(3+) is a reducing agent. (iv). both Cr and Mn are oxidizing agents. The correct statemetns are
