  1. An aqueous solution that conducts electricity, tastes sour, turns litmus paper red, and neutralizes bases Acids

  2. NomenclatureCommon Binary Acids: hydro- Cross over rule: • Hydrofluoric acid HF (aq) • Hydrochloric acid HCl (aq) • Hydrobromic acid HBr (aq) • Hydrosulfuric acid H2S (aq)

  3. Common Oxyacids (Polyatomic) • Acetic acid HC2H3O2 (aq) comes from acetate C2H3O2 – • Phosphoric acid (aq) comes from phosphate PO43-

  4. Try these: • Carbonic acid • Sulfuric acid

  5. Bases • An aqueous solution that conducts electricity and turns litmus paper blue • Usually a base is a metal and hydroxide • Cross over rule applies: • Sodium hydroxide is: • Calcium hydroxide is: • Magnesium hydroxide is: • Aluminum hydroxide is: • Ammonium hydroxide is:

  6. Power of Hydrogen: pH scalea very acidic solution has a low pH numbera very basic solution has a high pH numbera neutral substance has a pH of 7 (in the middle)
