To 555ml of a 0.435M Co(No3)3 solution, 445ml of a 0.120 M NaOH solution is added. Calculate the concentrations of Co+3 and Oh- in the solution at equilibrium at 20C regardless of whether precipitation occurs or not. I tried using the ice table but the instructor marked my answer wrong. Which Ksp should I use from the table and how would I properly calculate the concentrations
