  1. Common polyatomic ions



    Polyatomic Ion Charge = -1



    • acetate - C2H3O2-
    • bicarbonate (or hydrogen carbonate) - HCO3-
    • bisulfate (or hydrogen sulfate) - HSO4-
    • chlorate - ClO3-
    • chlorite - ClO2-
    • cyanate - OCN-
    • cyanide - CN-
    • dihydrogen phosphate - H2PO4-
    • hydroxide - OH-
    • nitrate - NO3-
    • nitrite - NO2-
    • perchlorate - ClO4-
    • permanganate - MnO4-
    • thiocyanate - SCN-

    Polyatomic Ion Charge = -2



    • carbonate - CO32-
    • chromate - CrO42-
    • dichromate - Cr2O72-
    • hydrogen phosphate - HPO42-
    • peroxide - O22-
    • sulfate - SO42-
    • sulfite - SO32-
    • thiosulfate - S2O32-

    Polyatomic Ion Charge = -3



    • borate - BO33-
    • phosphate - PO43-
  2. 7 strong acids
    • Hcl, Hbr, Hi
    • HNO3, H2SO4, HClO3, HClO4
  3. How to tell if something is an Acid
    It has an H infront of it i.e. HCl
  4. How to tell if you have a strong base
    the first two rows of the peirodic table, not including, "H" or the first three on the second row.

    • Take all those and put an "OH on them
    • Potassium hydroxide (KOH)
    • Barium hydroxide (Ba(OH)2)
    • Caesium hydroxide (CsOH)
    • Sodium hydroxide (NaOH)
    • Strontium hydroxide (Sr(OH)2)
    • Calcium hydroxide (Ca(OH)2)
    • Magnesium hydroxide (Mg(OH)2)
    • Lithium hydroxide (LiOH)
    • Rubidium hydroxide (RbOH)
  5. Three laws of theermodynamics
    1. energy can neither be created nor destroyed (the total amount of energy that exists is a constant) DeltaE=q+w

    2. Entropy (disorder) of the universe increases during spontaneous reaction. Delta S >or = q/t

    3. The entropy of any perfect crystal is zero (0) at the temperature of absolutue zero (0K or -273.15 C) aA+bB --> <-- cC+dD
