Cobalt cations (Co2+) complex with the thiocyanate anion(SCN-) similar to the way the Fe3+ cation does, but the cobaltcomplex is blue instead of being orange, as it is for iron. If anorange solution of Fe(SCN)2+ in equilibrium with Fe3+ and SCN- hada relatively small amount of Co2+ added, what would be theresult?
Some of the blue cobalt complex would form and changethe color, but the amount of iron complex would stay thesame.
The blue cobalt complex would form and a blue color willresult, with none of the iron complex left.
Some of the blue cobalt complex would form and changethe color, and the amount of iron complex would be decreasedsomewhat.
The cobalt complex would form and the iron complex woulddisappear completely, giving a nice blue color.
There would be no change in color, as the iron complexwas already present and in equilibrium with the thiocyanate whenthe cobalt was added.
