The task is to calculate the distribution of various cobalt species in solution based on their stability constants and concentrations. The goal is to find the percentage of the blue dithiocyanato cobalt(II) complex among all cobalt-containing species, which involves applying the stability constants to determine the concentrations of each complex formed. The answer to this calculation is 16.9%."}
