consider the following equilibrium: Mg(OH)2(aq) <-> Mg2+ (aq) + 2OH-(aq) a) what would happen to the equilibrium if some acid is added to the soultuion? --->OH- would increase causing Mg(OH02 to dissolve b) what would happen to the solubility of Mg(OH)2? ---> it wo...
Given a saturated solution of CaF2, write the ionic equilibrium and use it to calculate the solubility of CaF2. My answers for the ionic equation and ksp values are CaF2(s)<->Ca2+(aq)+ 2F-(aq) Ksp= [Ca2+][F-]2 ksp=2.02*10^-4 it asks what will happen to the value of ksp w...
