Why is CuS insoluble in water?

Since most anions are vulnerable bases, solubility is highly pH dependent. The basic anion would possibly develop into protonated in acidic answers, and thus the “insoluble” salt will dissolve. For instance, consider the solubility of CuS. This implies that sulfide ion is a slightly sturdy weak base, and will settle for protons.
