Assignment PreviewTemperature Depependence of Salt Solubility AK ChemistryTemperature Dependence of SaltSolubilityExperiment 11. Record your results for the four solubility temperatures of KCl as follows:aTemperature at which the solubility is 3.5g / 10 mL (C)23.1 C39.8 C bTemperature at which the solubility is 4g / 10mL (C)cTemperature at which the solubility is 4.5g / 10mL (C)56.8 CdTemperature at which the solubility is 5g / 10mL (C)74.8 C2. Convert your grams/10 mL values to grams/100 mL values and plot a solubility curve for potassium chloride. The horizontal axis is the temperaturescale in degrees C, and the vertical scale is the solubility in g/100 mL. 3.5g/10mL=35g/100ml temp=23.1 C4g/10ml=40g/100ml temp=39.8 C
4.5g/10ml=45g/100ml temp=56.8 C 5g/10ml=50g/100ml temp= 74.8 C3. Here is the official solubility data for KCl in grams/100 mL H2O:At 30C:37.1g/100ml H20At 50C:42.9g/100 ml H20At 70C:48.5g/100 ml H20At 90C:53.8g/100 ml H20Plot these points on a new graph.experimental solubulity 3.5g/10ml=35g/100ml=23.1 C4g/10ml=40g/100ml=39.8 C4.5g/10ml=45g/100ml=56.8 C5g/10ml=50g/100ml= 74.8 C4.
