Cobalt cations (Co2+) complex with the thiocyanate anion (SCN-)similar to the way the Fe3+ cation does, but the cobalt complex isblue instead of being orange, as it is for iron. If an orangesolution of Fe(SCN)2+ in equilibrium with Fe3+ and SCN- had arelatively small amount of Co2+ added, what would be theresult?
A) Some of the blue cobalt complex would form and change thecolor, but the amount of iron complex would stay the same.
B) The blue cobalt complex would form and a blue color willresult, with none of the iron complex left.C) Some of the blue cobalt complex would form and change the color,and the amount of iron complex would be decreased somewhat.
D) The cobalt complex would form and the iron complex woulddisappear completely, giving a nice blue color.
E) There would be no change in color, as the iron complex wasalready present and in equilibrium with the thiocyanate when thecobalt was added.
