  2. My numbering system Slide title: A, B, C… - Points on a slide: 1, 2, 3, - How to find it on your note handout: A1, A2, B1, B2…

  3. A. What you need to know? A1. What is a/an acid, base, salt? A2. How to name them A3. Acid, base, salt properties A4. Identify at least 3 products that are acids, bases, and salts used in daily life

  4. B. Common Acids

  5. C. What is an acid? C1. An acid is a compound that accepts pair of electrons. Commonly, most acid have proton (H+) in their chemical formula

  6. D.How to name acid D1. Inorganic acids (=no C, O in formula): Hydro---ic acid e.g.

  7. How to name acid (cont.) D2. Oxoacids (oxygen-containing acids): (Non-ate part)- ic acid

  8. How to name acid (cont.) D3. Oxoacids that are slight exceptions to the naming rules of: (Non-ate part)- ic acid

  9. E. Common Acid Properties • E1. Sour • E2. Corrosive • E3. Water-soluble • E4. Good electricity conductors

  10. F. Acids in everyday life F1.Carbonic acid (H2CO3) F2.Citric acid Also, ascorbic acid (Vitamin C)

  11. F. Acids in everyday life F4. Cheese (acetic acid) F3. Aspirin (acetylsalicylic acid) F5.Sour milk (lactic acid)

  12. F6. Sorbic Acid: a preservative

  13. G. Acids in the body G1.Heartburn: Caused by HCl from the stomach comes back up the esophagus

  14. H. Bee Sting and Formic Acid Formic Acid

  15. BASES

  16. I. Common Bases

  17. J. What is a base? J1. A base is a compound which donate pairs of electrons. Commonly, most bases have hydroxide (OH-) in their chemical formula

  18. K-How to name bases? Metal name first+ hydroxide e.g

  19. L. Common Acid Properties Bases: • L1. are bitter • L2. feel slippery • L3. are water-soluble • L4. are good electricity conductors

  20. M. Bases in everyday life M3. Baking soda (NaHCO3) M2. Windex (NH3) M1.Drain cleaners contains NaOH

  21. N. What would you do if? N1.Your car battery acid (H2SO4) is spilled?

  22. SALTS

  23. O. What is a salt? O1. Salts are composed of positively charged ion (cation) and negatively charged ion (anion) O2. A salt is formed when acid react with base E.g. CuSO4

  24. P. Applications of Salts P1. Soaps and Detergents

  25. P. Applications of Salts (cont.) P2. Fertilizer (e.g. Ammonium sulfate, magnesium sulfate)

  26. Q. Salt and our Canadian’s weather Q1. Why put salt on the sidewalk when it snows?

  27. Q. Salt and our Canadian’s weather Q1. Road salt helps reduce the freezing point of snow

  28. R. A Cultural Look at Food Preservation Table salts
