What is the cobalt (II) ion concentration in a solution prepared by mixing 451 mL of 0.395 M cobalt (II) nitrate with 457 mL of 0.296 M sodium hydroxide? The K_sp of cobalt (II) hydroxide is 1.3 times 10^-15 The balanced reaction for the precipitation of cobalt (II) hydroxide is Co^2+ (aq) + 2OH^- (aq) rightarrow Co (OH)_2 (s) Use this reaction to determine the limiting reactant. If hydroxide is the limiting reactant, then there will be excess cobalt (II) and the concentration of cobalt (II) in the final solution can be determined by dividing the number of excess moles of cobalt (II) by the total volume of the final solution in liters. If cobalt (II) is the limiting reactant, then there will be excess hydroxide and the K_sp expression for cobalt (II) hydroxide must be used to determine the cobalt (II) ion concentration of the final solution.
