The task is to calculate the percentage of the dithiocyanato cobalt(II) complex in a solution where cobalt concentration and thiocyanate concentration are known, along with the stability constants for various complexes. By applying the stability constants and the initial concentrations, we can determine the distribution of cobalt species and find the desired percentage of the blue dithiocyanato complex."}
