Cr2 is strong reducing agent
WebC r X 2 + gets converted to C r X 3 + as the +3 oxidation state has half-filled t 2 g orbitals; thus it is a good reducing agent. On the other hand M n X 3 + gets converted to M n X 2 … WebNov 3, 2024 · 1 Answer. Cr2+ has d4 configuration while Cr3+ has more stable d5 configuration. Thus, Cr has a tendency to acquire Cr3+ due to greater stability of +3 …
Cr2 is strong reducing agent
Did you know?
WebIn aqueous solution, Cr 2+ is a stronger reducing agent than Fe 2+. This is because: A Cr 2+ ion is more stable than Fe 2+. B Cr 3+ ion with d 3 configuration has favourable … WebCr 2+ is a stronger reducing agent than Fe 2+. This can be explained on the basis of the standard electrode potential values E° (Cr 3+ /Cr 2+ = –0.41 V) and E° (Fe 3+ /Fe 2+ = + 0.77 V). Thus Cr 2+ is easily oxidised to Cr 3+ but Fe 2+ cannot be as readily oxidised to Fe 3+. I hope this answer will help you. Thanks & Regards. Yash Chourasiya.
