The solubility of CuS in pure water is 3.3×10-4 g/L at 25℃. Using this number,calculate the apparent

The solubility of CuS in pure water is 3.3×10^-4g/L at 25℃. Using this number,calculate the apparent value of $The solubility of CuS in pure water is 3.3×10-4 g/$ for CuS. By precise measurement, the value of $The solubility of CuS in pure water is 3.3×10-4 g/$ for CuS at 25℃ is found to be 8.×10^-36. Explain why CuS is more soluble than predicted by the $The solubility of CuS in pure water is 3.3×10-4 g/$ .
