Experiment 1: Crystallisation of KNO3 - thermodynamics vs kinetics In this experiment, a beaker with a pre-weighed (-15 g) of potassium nitrate solid (KNO:) will be mixed with 25 ml of water, at a temperature > 60°C. Figure 1 shows the solubility curve for potassium nitrate (KNO:) solution as a function of temperature, which tells us the maximum mass of KNO, that can be dissolved in 100 g water, as a function of temperature. Figure 1: Solubility curve for aqueous KNO: Solubility Curve for KNO3 150 140 130 saturated! supersaturated 120 110 100 saturated 90 Solubility (grams of solute/100g H20) 80 70 60 50 unsaturated 40 30 20 10 0 0 0 10 20 30 40 50 60 70 80 90 100 Temperature (°C) (a) Using this Figure, calculate the minimum temperature of water required to dissolve 15 g of KNO, to form a saturated solution. Input your values into Lab 3 Results to see if they are correct estimates.
