Trying to name this compound and figure out its oxidation state
[ CoBr2(NH3)3(H2O) ]+
I came up with triammineaquadibromocobalt(II) ion with a +3 oxidation state...but not sure if this is right...
I came up with tetrachlorooxalatoferrate(IV) ion guessing that the oxidation state is +4 but I don't think this is right...having trouble with naming, clearly. Any help is appreciated :)
#1 looks ok to me except the oxidation state of Co is +3 and not +2. (+3 Co + (-2) for 2Br = +1 for the ion.
#2 I would do it a little differently.
The parentheses around oxalato are not accidental. Check my thinking.
