  4. Substance turns litmus paper red

  5. Acid

  6. Substance that turns litmus paper Blue

  7. Bases

  8. Substance that turns phenolphthalein bright pink

  9. Bases

  10. Phenolphthalein is clear or coudy in this solution

  11. Acids

  12. Substance that turns blue litmus paper blue and red litmus paper red

  13. A neutral substance. Water

  14. pH scale 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 C D B E A • What letter would represent a weak acid? • What letter would represent a strong acid?

  15. D Weak acids have a pH around 3-6.9 C Strong acids have a pH around 0-3

  16. pH scale 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 C D B E A What letter would represent a strong base?

  17. A Strong bases have a pH around 10-14

  18. pH scale 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 C D B E A • What letter would stomach acid represent on the pH scale? • What letter would soap represent on the pH scale?

  19. C Stomach acid contains HCl which is a strong acids E Soap is a weak base

  20. pH scale 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 C D B E A If we combine substance C and A, what letter would correspond the to correct pH.

  21. B Combining a strong acid and a stong base will neutralize each other and create a neutral substance.

  22. pH scale 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 C D B E A If we combine substance C and E, what letter would correspond the to correct pH.

  23. D Combining a strong acid and weak base will create a weak acid.

  24. Substances that tastes sour

  25. Acids (lemons, limes, oranges)

  26. Substance that is slippery

  27. Bases (soap is a weak base)

  28. Substance that tastes Bitter

  29. Base

  30. Substance that emulsifies fats and oils.

  31. Base For example, soap breaks apart fats and oils to make you’re your dishes clean.

  32. Substance that dissolves in water to produces positive hydrogen (H+) ions

  33. Acids break apart in water to produce H+ ions.

  34. Substance that dissolves in water to produces hydroxide (OH-) ions.

  35. Bases produce OH- ions. OH- combines with a H+ from acids to form water

  36. When you combine an acid and a base, what do you form?

  37. 2 neutral substances. Water and a salt

  38. What type of reaction is a neutralization reaction?

  39. Double replacement reaction.

  40. Finish the reaction. 2HBr  +  Ba(OH)2 ____2  +  2___

  41. 2HBr  +  Ba(OH)2BaBr2  +  2H2O Neutralization reaction a type of salt water

  42. What is heartburn? • What can you do to relieve the discomfort?

  43. Stomach acids that enter the esophagus and eat away at the tissue which causes discomfort. • An antacid will neutralize the stomach acid and relieve the discomfort.

  44. a) Acids always start with what? b) Bases usually end with what?

  45. Acids start with H. • For example: HCl and H2SO4 • Hydrochloric and sulfuric acid • b) Bases usually end with OH • For example NaOH and KOH

  46. What causes acid rain?

  47. Cars burn gasoline to produce NO2 Factories and power plants burn coal to produce SO2 Write down the Jeopardy question and answer. Hand in before the test for extra credit.

  48. What are 2 things you can do to prevent acid rain?

  49. Walk more and ride your bike instead of having your parents give you a ride. Carpool or take a bus. (etc) Use less energy. Turn off the lights when leaving a room or turn off your computer at night. (etc)

  50. What are 2 ways companies are reducing the amount of acid rain?
