  9. What makes water an effective solvent?

  10. Its Polar Nature

  11. What characteristic of water remains the same no matter what is dissolved in it?

  12. The ratio of hydrogen to oxygen

  13. Hard water has a pH higher than 7 and an abundance of calcium and magnesium salts. What would be the best cleaning solution for removing hard-water residue from drinking glasses?

  14. A mild acid such as vinegar

  15. Explain in detail what makes a water molecule polar. Double the score if correct!

  16. Oxygen has greater electronegativity so it doesn’t share electrons equally, oxygen keeps the electrons most of the time

  17. The picture shows the results of pouring a blue liquid into a clear liquid and allowing the mixture to settle for 25 minutes. Why did the solution end up looking like this?

  18. 2 Liquids are immiscible and the blue one has a higher density

  19. What is an electrolyte?

  20. A solution that conducts electricity.

  21. What process is depicted in the following picture?

  22. Dissociation

  23. Why does dissolving salt in water increase the conductivity of the solution?

  24. concentration of ions in the solution increases

  25. Why will bathwater normally have electrolytic behaviors even though distilled water does not?

  26. Bathwater generally contains dissolved minerals

  27. Why doesn’t pure water conduct electricity?

  28. No Ions or minerals are dissolved in it

  29. A true solution is a homogeneous mixture and it has to also be __________________

  30. Colorless or transparent

  31. What will be the pH of asolution having an equal number of H+ ions and OH– ions?

  32. pH = 7

  33. What does the following symbol stand for? [H3O+]

  34. [H3O+] Hydronium Ion Concentration

  35. What does the following symbol stand for? [OH-]

  36. [OH-] Hydroxide Ion Concentration

  37. Write down the 3 factors that influence the RATE of dissolving?

  38. Temperature • Agitation / Stirring • Surface Area of Particles

  39. Which choice has the most surface area? A B or

  40. Choice B

  41. Which of the following choices will dissolve more salt? 50˚ 100˚

  42. For solids, as temperature increases solubility increases.

  43. What can you do to liquid soda to get it to dissolve more carbonated gas (CO2)?

  44. Lower the Temperature

  45. What does it mean to be miscible?

  46. That substances are able to mix together

  47. What are the 3 factors affecting solubility?

  48. Nature of the Solvent • Pressure (gases only) • Temperature

  49. Why would swimmers say that they can float more easily in the ocean than in a freshwater pond?
