“You have a solution of potassium nitrate (KNO₃) in water. Describe the steps you would take to obtain pure crystals of potassium nitrate from this solution using crystallization. A company is trying to obtain pure copper(II) sulfate (CuSO₄) crystals from a solution. They are concerned that heating the copper(II) sulfate too much might cause it to decompose. Which separation technique, evaporation or crystallization, would be more suitable in this situation, and why?”
