Cr2+ is a stronger reducing agent than Fe2+ .why?
plz ans in short
There are two reason for Cr3+ to be more reducing than Fe2+:
- The electrode reduction potential values are:
- As we know that, the more negative the electrode potential greater is the reducing power of the electrode.
- The highest oxidation state for Cr is +6, therefore it can loose 3 more electrons, whereas Fe needs to loose only 1 electron to achieve its highest oxidation state of +3. Thus, Cr3+ is more reducing than Fe2+.
