Investigating Solubility How does the solubility of Potassium Chloride and Potassium Iodide in water, vary with temperature?

How does the solubility of green Chloride (KCl) and Potassium Iodide (KI) in wet channelize with temperature?AimTo observe solubilities of KCl and KI with water at different temperaturesTo proportion the two solubility curves and discuss what might vary the solubility of different ionic compounds. The variablesDependent variableTemperatureIndependent variableAmount of solute (KCl, KI)ConstantsAmount of the solvent (water), pressureApparatus? light speedg of Potassium Chloride?100g of Potassium Iodide?10ml cylinder?Test tubes x 15?Stoppers?Glass celestial pole?Beakers x 5?Distilled water?Spatula?Hot plate?crank ? to cool it down the water?Thermometer (0°C to 100°C) x 2MethodIn this try different amount of solute were combined with 10ml of water (solvent) which to begin with was at 0°C. The solvent and solute were mixed to fither and the temperature where the solute is exclusively crook to the solvent is measured. 1.Weigh different amounts of KCl and KIKCl ? 6g, 7g, 8 g, 9g, 10g (approx.)KI ? 12g, 14g, 16g, 20g, 25g (approx.)2.Measure 10ml of water and place them into running receive tubes3.Place the test tubes into ice and wait till they cool to 0°C4.Start breakup the substances into cooled distilled water with the smallest amount of substances5.Use a glass rod to submit or a stopper to shake6.Measure the temperature at where the substances atomic number 18 covmpletely dissolved7.Repeat the carry through for each gram of the substances ? use blue plates with water bathing tub on top where hold to get higher temperature.
