What is the oxidation state of CO in [CO(H_(2)O)_(5)CI]^(2+) ?

1.	What is the oxidation state of CO in [CO(H_(2)O)_(5)CI]^(2+) ?
Answer» `+2` `+3` `+1` `+4` Solution :Since `H_(2)O` is a NEUTRAL molecule sum of its O.N is zero WHIL O.N of CI is -1 now x is the O.N of Co then `x+5xx0+(-1)=+2` `THEREFORE x=+2+1=+3`
