5. Template by Bill Arcuri, WCSD What does dissolve in water mean?

6. Template by Bill Arcuri, WCSD Dissolve in water means that the ions of the compound break up when put in water

7. Template by Bill Arcuri, WCSD What is an electrolyte?

8. Template by Bill Arcuri, WCSD An electrolyte is a compound that dissolves in water

9. Template by Bill Arcuri, WCSD What are unsaturated, saturated, and supersaturated solutions?

10. Template by Bill Arcuri, WCSD Unsaturated means that more solute can be added, saturated means that a solution has dissolved all the solute it can hold, supersaturated means that due to an increase in heat a solution has more solute dissolved than it can normally hold.

13. Template by Bill Arcuri, WCSD What is the formula for vinegar and what kind of electrolyte is it? Why?

14. Template by Bill Arcuri, WCSD The formula is HCH 3 COO and it is a weak electrolyte because the not many H + ions dissociate.

19. Template by Bill Arcuri, WCSD Find the %(W/V) for 60 g of solute in.6 L of a solution

20. Template by Bill Arcuri, WCSD 10%(W/V) Don’t forget to convert to milliliters for %(W/V)

21. Template by Bill Arcuri, WCSD Find the molarity of 5.6 g of lead nitrate in 400 mL water

22. Template by Bill Arcuri, WCSD 5.6 g x (l mol/331.2 g/mol) =.0169 mol..0169 mol/.4 L =.0423 M

23. Template by Bill Arcuri, WCSD Daily Double!!! What is the total ion molarity for 6.7 g of Ammonium Sulfide in 5 L of water?

24. Template by Bill Arcuri, WCSD 6.7 g x (1 mol Ammonium Sulfide/ 68.154 g/mol) =.0983 mol.0983 mol x 3 ions =.295 mol

25. Template by Bill Arcuri, WCSD What is a solute?

26. Template by Bill Arcuri, WCSD A solute is the chemical that is dissolved

27. Template by Bill Arcuri, WCSD If 11 moles of NaCl are dissolved in 330 kg of water, what is its molality?

28. Template by Bill Arcuri, WCSD.033 m

29. Template by Bill Arcuri, WCSD When magnesium chloride is placed into water, it seems to disappear. Does it disappear? If not, why does it seem this way?

30. Template by Bill Arcuri, WCSD Magnesium chloride does not disappear when put in water, the particles are just surrounded by water and too tiny to see.

31. Template by Bill Arcuri, WCSD What is hydration and ionization?

32. Template by Bill Arcuri, WCSD Hydration is what occurs when an ionic compound dissolves in water, ionization is the process of breaking up the compound into separate ions.

33. Template by Bill Arcuri, WCSD What kind of electrolytes conduct electricity well? Why?

34. Template by Bill Arcuri, WCSD Strong electrolytes conducted electricity better because they make free- floating ions in water.

35. Template by Bill Arcuri, WCSD What is a precipitate?

36. Template by Bill Arcuri, WCSD A precipitate is an insoluble compound that does not dissolve in water

37. Template by Bill Arcuri, WCSD If silver nitrate was mixed with sodium chloride, would a precipitate form?

38. Template by Bill Arcuri, WCSD Yes, AgCl would precipitate

39. Template by Bill Arcuri, WCSD Indicate what precipitates forms, if any: NaNO 3 + Li 2 CO 3

40. Template by Bill Arcuri, WCSD No precipitate forms

41. Template by Bill Arcuri, WCSD Indicate what precipitates forms, if any: Ca(CH 3 COO) 2 + Na 3 PO 4

42. Template by Bill Arcuri, WCSD Ca 3 (PO 4 ) 2 would form

43. Template by Bill Arcuri, WCSD Indicate what precipitates forms, if any: Magnesium iodide and mercury (I) flouride

44. Template by Bill Arcuri, WCSD Hg 2 I 2 and MgF 2 would form

45. Template by Bill Arcuri, WCSD What is the difference between pH and pOH?

46. Template by Bill Arcuri, WCSD pH is a measure of the H + concentration and pOH is a measure of the OH - concentration

47. Template by Bill Arcuri, WCSD If there are.006 mol of H + in 2 L of water, what is the H + concentration?

48. Template by Bill Arcuri, WCSD.006 mol/2 L =.003 M H +

49. Template by Bill Arcuri, WCSD If the pH increase by 2, what happens to the H + concentration?

50. Template by Bill Arcuri, WCSD It decreases by 100

51. Template by Bill Arcuri, WCSD What is the H + concentration if the pOH is 8.6?

52. Template by Bill Arcuri, WCSD 14 – 8.6 = 5.4 pH = 5.4 10 -5.4 = 3.98 x 10 -6

53. Template by Bill Arcuri, WCSD If.05 moles of HCl are put in 60 L of water, what is the pH? Daily Double!!!

54. Template by Bill Arcuri, WCSD.05 moles / 60 L = - 8.33 x 10 -4 M 10 (-8.33 x 10-4) = 3.08

63. Template by Bill Arcuri, WCSD If you frequently have heartburn, would putting ketchup on your French fries increase or decrease the odds of you getting heartburn? Why?

64. Template by Bill Arcuri, WCSD It would increase your odds of getting heartburn because ketchup has vinegar (acetic acid), which is acidic.

65. Template by Bill Arcuri, WCSD Final Jeopardy If.5 mol H 2 SO 4 dissolved in 30 L of water is added to 2 mol HCl dissolved in 10 L of water, what is the pOH?

66. Template by Bill Arcuri, WCSD Click Once to Begin.5 mol / 40 L =.0125 M x 2 H + =.025 M H + in H 2 SO 4 2 mol / 40 L =.5 M H + in HCl..025 M H + in H 2 SO 4 +.05 M H + in HCl =.075 M H + total. -log(.075 M) = 1.12 14 – 1.12 = 12.87 pOH = 12.87
