You desolve 3mmol of Mg(OH)2 into 300 ml of water. Mg(OH)2 will dissociate into Mg2+ & 2 OH-. How many ml of water must be added to make this sollution to have [OH-] = 1mM? hint: This one is difficult. You need to realize [OH-] is not same as [Mg(OH)2]. So get the concentration of [OH-]. Then, use dilution formula. C1V1=C2V2. Amount of water added must be Vfiinal-Vinitial. 1000ml 3000ml 6000ml 9000ml
