SUMMARY
The discussion focuses on recovering potassium nitrate (KNO3) from an aqueous solution by cooling it from 60°C to 10°C. The initial solution consists of 250g of KNO3 dissolved in 250g of water. To determine the mass of KNO3 that can be recovered, one must first establish the solubility of KNO3 at 10°C. The solubility data indicates that KNO3 has a significantly lower solubility at 10°C compared to 60°C, which directly impacts the amount that can be crystallized out of the solution.
