What is the pH value of copper sulphate?

Donald Hubbs  Follow

you cant find a pH value of copper sulphate without knowing its concentration and the Ka, acid dissociation constant. But it is a salt of a strong acid and weak base hence can produce an acidic solution by salt hydrolysis.

pH only indicates the concentration of H+ in solution. By itself, it does not measure the extent of acid dissociation.

A much diluted solution of a strong acid such as HCl acid may give a relatively high pH value and conversely for a very concentrated solution of a weak acid such as ethanoic acid may be relatively low pH value.

Funny how correct answers can be so wrong.  Yes it was a poorly worded question but it can be answered with constraints of, "in an aqueous solution near saturation at room temp."More

Copper sulphate is a solid salt. A salt doesn't has a pH.

The pH is only defined for aqueous solutions, so unless you mean to ask about the pH of an aqueous solution of copper sulfate, the answer is “there is no pH".
