Warm-up:Concept: PS-3.1 Solubility

REMEMBER: The solubility of a solute is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature.

1.1. What is the solubility What is the solubility of NaCl at 75of NaCl at 75ooC?C?

2.2. How much Potassium How much Potassium Iodide could you Iodide could you expect to dissolve in expect to dissolve in water at 37water at 37ooC?C?

3.3. At what solvent At what solvent temperature do temperature do Sodium Nitrate and Sodium Nitrate and Potassium Nitrate Potassium Nitrate have the same have the same solubility?solubility?

4.4. Which of the Which of the compounds shown on compounds shown on this graph illustrates this graph illustrates a direct proportion a direct proportion between solvent between solvent temperature and temperature and solubility?solubility?
