  1. Acid base definitions
    • Arrhenius: Acids produce [H+] ions in solution and bases produce [OH] ions in solution
    • Bronstead-Lowry: Acids donate protons [H+]; bases accept protons [H+].
    • Lewis: Acids accept a pair of electrons; bases donate a pair of electrons.

    Amphoteric substances can act as either an acid or a base. (e.g. H2O)
  2. pH scale
    • pH = –log[H+]
    • pOH = –log[OH]
    • pH + pOH = 14
  3. Strong Acids
    • HI
    • HBr
    • HCl
    • HNO3
    • HClO4
    • HClO3
    • H2SO4

    Polyprotic acids: acids with more than one acidic proton like sulfuric acid. The second proton is always significantly less acidic.
  4. Strong Bases
    • Group IA hydroxides (NaOH, KOH, etc.)
    • NH2
    • H
    • Ca(OH)2
    • Na2O
    • CaO
