Homework Help: Mass balance/Charge balance

  1. Apr 13, 2007 #1
    Can somebody explain how do you write a Mass Balance or Charge balance for a acid-base equilibrium? Let say, if you are given 0.01M Zn(OH)2 in a saturated NaOH solution and also given that Zn(OH)2 + 2OH- -> Zn(OH)4(2-) how would you solve the mass balance/charge balance? I really have no idea how to do these types of quesitons....Thanks!!
