Thank you everyone! I understand now, I was just making it more complicated in my head.
There's one last one if you can help:
Mg(OH)2 - - > Mg2+ + 2 OH-
What would happen to the position of the equilibrium and amount of mg(oh)2 if you add HCl?
So I think the 2OH- and the 2H+ would make H2O, and the Mg2+ and 2Cl- would make MgCl2. So this would essentially decrease the amount of Mg(OH) 2 solid. So the equilibrium would move to the right, to the products side?
Is this correct?
