  1. Acid Base Reactions
    • Arrhenius Acid
    • Arrhenius Base
    • Bronsted Acid
    • Bronsted Base
  2. Arrhenius Acid
    produces H+ in aq solutions
  3. Arrhenius Bases
    produce OH- in aq solutions
  4. Bronsted Acid
    Donates a proton (H+)
  5. Bronsted Base
    Accepts a proton (H+)
  6. What actually happens...
    HF(aq) + H2O(aq) ⇌ H+(aq) + F- 

    • HF = Arrhenius and Bronsted Acid
    • H2O = Bronsted Base
  7. Acids # of protons donated
    • Monoprotic 1 
    • Diprotic 2
    • Triprotic 3
    • Polyprotic ≥2
  8. Acid Base neutralization Reaction


    salt is an ionic compound btw
  9. Oxidation Reaction Reactions (Redox Reactions)
    electrons are transferred between the reactants
  10. Oxidized
    • loses electrons 
    • LEO loses electrons oxidized
  11. Reduced
    • gains electrons 
    • GER gains electrons reduced
  12. half reactions
    literally show half of what's going on...
  13. Oxidation #'s
    charge an atom would have if e- were completely transferred
  14. Guidelines for Oxidation #'s
    • element/elemental form are NOT oxidized (so 0) 
    • sum of oxidation number on a molecule = charge on molecule
  15. Concentration
    • amount of solute dissolved in a given amount of solvent 
    • Molarity M = moles of solute/1 L solution
  16. Dilution
    Concentration (stock) → less concentrated (dilute)

    C1V1 = C2V2

     stock = dilute

    C = concentration in M and V = volumes
  17. Parts per Million (ppm)
    1mg/1L
  18. PH scale (H= H3O)
    • PH = -log [H+]
    • unitless

    • 1-7 acid 
    • 7-14 base
    • 7 neutral
  19. To determine [H3O+] from PH
    [H3O+] = 10-ph
  20. Acid Base Titration bos
    Vol A, M A, mol A, mol:mol, mol B, M B, vol B
