Why is CuS insoluble in water?
Since most anions are weak bases, solubility is highly pH dependent. The basic anion may become protonated in acidic solutions, and thus the “insoluble” salt will dissolve. For example, consider the solubility of CuS. This means that sulfide ion is a relatively strong weak base, and will accept protons.
