The correct statements about Cr2+ and Mn3+ is(are) (Atomic numbers of Cr = 24 and Mn = 25)
Multiple Choice Options
- A Cr2+ is a reducing agent.
- B Mn3+ is an oxidizing agent.
- C both Cr2+ and Mn3+ exhibit d4 electronic configuration.
- D when Cr2+ is used as a reducing agent, the chromium ion attains d5 electronic configuration.
Step-by-Step Verified Solution
The correct statements are as follows:
(A) Cr3+ is more stable than Cr2+, thus, Cr2+ act as reducing agent.
(B) Mn2+ is more stable than Mn3+, thus, Mn3+ act as an oxidizing agent.
(C) Both Cr2+ and Mn3+ exhibit d4 electronic configuration.
