  3. What does dissolve in water mean?

  4. Dissolve in water means that the ions of the compound break up when put in water

  5. What is an electrolyte?

  6. An electrolyte is a compound that dissolves in water

  7. What are unsaturated, saturated, and supersaturated solutions?

  8. 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.

  9. Break up (NH4)3PO4 into ions

  10. 3NH4+ + PO43-

  11. What is the formula for vinegar and what kind of electrolyte is it? Why?

  12. The formula is HCH3COO and it is a weak electrolyte because the not many H+ ions dissociate.

  13. If you 2.5 moles of Na+ is dissolved in 5 L of water, what is the molarity?

  14. .5 M Na+

  15. What is the molarity of Cl- in 1.2 M CaCl2?

  16. 2.4 M Cl-

  17. Find the %(W/V) for 60 g of solute in .6 L of a solution

  18. 10%(W/V) Don’t forget to convert to milliliters for %(W/V)

  19. Find the molarity of 5.6 g of lead nitrate in 400 mL water

  20. 5.6 g x (l mol/331.2 g/mol) = .0169 mol..0169 mol/.4 L = .0423 M

  21. Daily Double!!! What is the total ion molarity for 6.7 g of Ammonium Sulfide in 5 L of water?

  22. 6.7 g x (1 mol Ammonium Sulfide/68.154 g/mol) = .0983 mol.0983 mol x 3 ions = .295 mol

  23. What is a solute?

  24. A solute is the chemical that is dissolved

  25. If 11 moles of NaCl are dissolved in 330 kg of water, what is its molality?

  26. .033 m

  27. When magnesium chloride is placed into water, it seems to disappear. Does it disappear? If not, why does it seem this way?

  28. Magnesium chloride does not disappear when put in water, the particles are just surrounded by water and too tiny to see.

  29. What is hydration and ionization?

  30. Hydration is what occurs when an ionic compound dissolves in water, ionization is the process of breaking up the compound into separate ions.

  31. What kind of electrolytes conduct electricity well? Why?

  32. Strong electrolytes conducted electricity better because they make free-floating ions in water.

  33. What is a precipitate?

  34. A precipitate is an insoluble compound that does not dissolve in water

  35. If silver nitrate was mixed with sodium chloride, would a precipitate form?

  36. Yes, AgCl would precipitate

  37. Indicate what precipitates forms, if any:NaNO3 + Li2CO3

  38. No precipitate forms

  39. Indicate what precipitates forms, if any:Ca(CH3COO)2 + Na3PO4

  40. Ca3(PO4)2 would form

  41. Indicate what precipitates forms, if any:Magnesium iodide and mercury (I) flouride

  42. Hg2I2 and MgF2 would form

  43. What is the difference between pH and pOH?

  44. pH is a measure of the H+ concentration and pOH is a measure of the OH- concentration

  45. If there are .006 mol of H+ in 2 L of water, what is the H+ concentration?

  46. .006 mol/2 L = .003 M H+

  47. If the pH increase by 2, what happens to the H+concentration?

  48. It decreases by 100

  49. What is the H+ concentration if the pOH is 8.6?

  50. 14 – 8.6 = 5.4pH = 5.410-5.4 = 3.98 x 10-6
