  1. ACIDS, BASES and SALTS

  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 a pair of electrons. Usually, most acid have proton (H+) in their chemical formula

  6. D.How to name acid D1. Binary acids containing no oxygen Hydro(element root)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. Try again

  10. Naming binary acid RULE 1: hydro(element root)icacid Examples: HCl is hydrochloric acid HBr is hydrobromic acid HI is hydroiodic acid HF is hydrofluoric acid

  11. Naming oxoacid RULE 2: -ATE becomes -ICacid

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

  13. F. Acids in everyday life F1.Phosphoric acid (H3PO4) F2.Citric acid Also, ascorbic acid (Vitamin C)

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

  15. F6. Sorbic Acid: a preservative

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

  17. H. Bee Sting and Formic Acid Formic Acid

  18. BASES

  19. I. Common Bases

  20. J. What is a base? J1. A base is a compound which donate a pair of electrons. Usually, most bases are made up of a metal ion and a hydroxide (OH-) in their chemical formula

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

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

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

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

  25. SALTS

  26. O. What is a salt? O1. Salts are ionic compounds composed of a metal ion and a non-metal ion O2. A salt is formed when acid react with base E.g. CuSO4

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

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

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

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

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