1. Solubility

2. Solubility Curves show how much solute will dissolve in water at a given temperature Table G shows a solubility curve

3. Solubility Curves for Gases As temperature goes up, gases become less soluble in water

4. Solubility Curves for solids As temperature goes up, solids become more soluble in water

6. How many grams of potassium nitrate will dissolve in 100 g of water at 50 degrees C? 85 grams

7. How many grams of potassium nitrate will dissolve in 300 g of water at 50 degrees C? 85 grams x 3 = 255 grams

8. How many moles of potassium nitrate will dissolve in 100 g of water at 50 degrees C? 85 grams = ? moles K = 39g N = 14 g O 3 = 48g KNO 3 = 101 g/mol 85g/101g/mol =.84 moles

9. X On the curve = Saturated solution

10. X Under the curve = Unsaturated solution

11. X Above the curve = Supersaturated solution

13. X X If 130g of NaNO 3 are added to 100 g of water, how many grams will NOT dissolve?

14. X X If 130g of NaNO 3 are added to 100 g of water at 30 degrees, how many grams will NOT dissolve? 92 grams will dissolve 130-92 = 38 g won’t

15. X
