The desired product is isolated from its impurities by differences in solubility. Insoluble impurities and colored impurities can be removed from hot solvent through the use of activated carbon and filtration. Soluble impurities remain in the cold solvent after recrystallization. The desired product should be as soluble as

King Arthur and the Knights of the Round Table: An Epic Hero for Modern Times In about 1470‚ Thomas Malory finished Morte d’ Arthur‚ the first of the many legends written about King Arthur. Even in modern times‚ King Arthur and the Knights of the Round Table are a favorite subject in movies‚ books‚ and plays. Often times this is so because the Medieval Period in general‚ and King Arthur in particular‚ have an air of mystery‚ romance‚ fantasy‚ and adventure that are popular themes in all times

CM1191 Experiment 1: Study of Solubility Equilibrium 1. Abstract The aim of this experiment is to determine the relationship between the solubility of potassium hydrogen tartrate (KHC4H4O6) and temperature. Titrate a known concentration of NaOH against a saturated solution of KHC4H4O6 at different temperatures to obtain the concentrations of KHC4H4O6‚ and hence the solubility product constant of KHC4H4O6 at various temperatures. It was found that the solubility product constant of KHC4H4O6
