2. 2 What is the order from most acidic to most basic for the following: Soap, stomach acid, battery acid, orange juice, water, ammonia

3. 3 Battery acid, stomach acid, orange juice, water, soap, ammonia

4. 4 What molecule is present in acids

5. 5 H +

6. 6 What molecule is present in bases

7. 7 OH -

8. 8 What is the range for pH and What are characteristics of acids and bases

9. 9.1-14 with.1 being the most acidic and 14 being the most basic

10. 10 Name 3 heavy metals and their affects on living thing Also, state where living things could be exposed to the metals

11. 11 I’ll just look at your answers!

12. 12 What is a supersaturated solution and give an example

13. 13 A solution that has more solute than normally dissolved in it at standard temperature Example: 15 grams of sodium acetate in 3ml of water Or the sugar solution to make rock candy

14. 14 Does an unsaturated solution have no solute in it?

15. 15 No…it just isn’t saturated

16. 16 Draw a solution of saturated salt water

17. 17 I’ll look at your answers Here is an example:

18. 18 What is the percent by mass of sugar in a solution that has 132 grams of sugar That is dissolved in 750 grams of water.

19. 19 15%

20. 20 Describe the basic procedure you performed in the saturation lab…be thorough it is a 25 pt question!

21. 21 I’ll read your answers

22. 22 Saturation of a solid in a liquid increases or decrease as temperature rises

23. 23 increases

24. 24 Saturation of a gas in a liquid increases or decreases as temperature rises

25. 25 decreases

26. 26 What dissolved gas is crucial to fish in the water

27. 27 Dissolved Oxygen

28. 28 What affect does pressure have on the solubility of a gas in a liquid and why does warm pop fizz when opened more than cold pop

29. 29 The solubility increases with pressure and warm pop fizzes more because warm pop can hold less carbon dioxide gas so the gas releases when opened (the pressure releases)

30. 30 What is the saturation point (grams of substance that can fit into 100grams of water) at 40 degrees C on the solubility curve on page 62

31. 31 40 grams of KCl

32. 32 How does natural water purification work

33. 33 Lets Look

34. 34 How does municipal/city water purification work?

35. 35 Lets Look

36. 36 Why would a city water treatment plant put fluoride in the water?

37. 37 To help strengthen the enamel of your teeth.

38. 38 What is bacterial action

39. 39 Converts dissolved organic contaminants into a few simple compounds

40. 40 Chlorination of water decreased what problem?

41. 41 Bacterial diseases in drinking water due to human waste in the system

42. 42 How is evaporation like distillation?

43. 43 Both cause the water to be pulled away from the heavy contaminants
