Solve for hydrogen ion concentration: Finally, calculate the pH: pH = - log[H+] = - log(0.027) = 1.57. This pH represents the maximum pH which must be maintained in order to separate nickel(II) ions and copper(II) ions. Since the sulfide ion concentration is 1.5 x 10-18 M, the actual copper ions concentration still remaining in solution is:
