    You will have to look at each individual equation.

    For example, consider the well-known

    [Cu(H2O)6]2+ + 4NH3 <-----> [Cu(NH3)4]2+ + 6H2O.

    You might not think that this was pH dependent from the equation, but adding an acid will make it go to the left. This is because H+ ions react with the free NH3 molecules, lowering their concentration. Le Chatelier's Principle then says that the equilibrium will move to the left to raise their concentration again.
