Magnesium hydroxide is used in several antacid formulations. When it is added to water it dissociates into magnesium and hydroxide ions.                            Mg(OH)2(s)  —->   Mg2+(aq) + 2OH–(aq) The equilibrium constant at 25°C is 8.9 x 10–12. One hundred grams of magnesium hydroxide is added to 1.00 L of water and equilibrium is established. What happens to the solution if another 10 grams of Mg(OH)2 are now added to the mixture?
