Copper sulfate is pretty soluble and if the pH is kept less than 7, the pH would have a small unpredictable effect. If a lot of sulfuric acid is used the solubility will be decreased by the addition of a common ion "(SO4)^-2" but this would require a very low pH.

pH of 0.1 M CuSO4=4.58
As it is a weak base, it will not grab H+ from the environment. On its part, Cu2+ will strongly attract OH− groups, and overall protons will prevail over hydroxides.
