Assignment Preview Temperature Depependence of Salt Solubility AK Chemistry Temperature Dependence of Salt Solubility Experiment 1 1. Record your results for the four solubility temperatures of KCl as follows: a Temperature at which the solubility is 3.5g / 10 mL (C) 23.1 C 39.8 C b Temperature at which the solubility is 4g / 10mL (C) c Temperature at which the solubility is 4.5g / 10mL (C) 56.8 C d Temperature at which the solubility is 5g / 10mL (C) 74.8 C 2. Convert your grams/10 mL values to grams/100 mL values and plot a solubility curve for potassium chloride. The horizontal axis is the temperature scale in degrees C, and the vertical scale is the solubility in g/100 mL. 3.5g/10mL=35g/100ml temp=23.1 C 4g/10ml=40g/100ml temp=39.8 C

4.5g/10ml=45g/100ml temp=56.8 C 5g/10ml=50g/100ml temp= 74.8 C 3. Here is the official solubility data for KCl in grams/100 mL H 2 O: At 30C: 37.1g/100ml H20 At 50C: 42.9g/100 ml H20 At 70C: 48.5g/100 ml H20 At 90C: 53.8g/100 ml H20 Plot these points on a new graph. experimental solubulity 3.5g/10ml=35g/100ml=23.1 C 4g/10ml=40g/100ml=39.8 C 4.5g/10ml=45g/100ml=56.8 C 5g/10ml=50g/100ml= 74.8 C 4. Obtain the solubility of potassium chloride in g/100 mL of H
