...n will be converted to Sn+4 during the reflux process.

2) Acetone and water are very miscible together, meaning the acetone and water will mix without a problem. The solubility comparison therefore has to be between the pure water or water with KI. The solubility of KI in acetone is very low, so the saturated KI solution ...
