Which is stronger reducing agent Cr2+ or Fe2+ ?
A compound of vanadium has a magnetic moment of 1.73 B.M.Work out the electronic
configuration of vanadium ion in the compound.
The transition metals generally form coloured compounds.​

Answer 1

Explanation:

1)Cr2+ is a stronger reducing agent than Fe2....

Reason. This can be explained on the basis of the standard electrode potential values E°(Cr3+/Cr2+ = –0.41 V) and E° (Fe3+/Fe2+ = + 0.77 V). Thus Cr2+ is easily oxidised to Cr3+ but Fe2+ cannot be as readily oxidised to Fe3+.
