More on Temperature and Solubility - Data Sheet

  1. While the water in the beaker was heating, did both the solids in the test tubes dissolve at the same rate or at different rates?

     

     

  2. Describe what happened when the two test tubes were placed in the beaker of cold water.

     

     

  3. If 5 grams of potassium nitrate (KNO3) were dissolved in 10 mL of water at room temperature, how much could be dissolved in 100 grams of water at the same temperature?

     

     

  4. Solubility depends on three factors: the nature of the solvent, the nature of the solute and the temperature of the solution. Which factor was the variable in this experiment?
