  1. Solubility rules
    1. All group 1 elements are soluble. 2. Ammonium ions are souble. 3. nitrates are soluble. 4. acetates are soluble 5. chlorates and percholrates are soluble 6. Chlorides, bromides, and iodides are soluble except when with Ag+, Hg2(2+), or Pb2+. 7. Sulfates are soluble except with Ca2+, Sr2+, Ba2+,Pb2+, Hg2(2+), and Ag+.
  2. Insolubility rules
    Carbonates are usually not soluble except when with ammounium ions or group 1 elements. Phosphates are insouble except with ammonium ions or group 1 elements. Sulfites are insoluble excpet when with group 1 or 2 metals and ammonium. Hydroxides are generally not soluble except with group 1 and 2 metals or ammonium.
  3. Strong acids
    • HClO4- perchloric acid HCl hydrochloric acid
    • HClO3- chloric acid H2SO4 sulfuric acid
    • HBr hydrobromic acid HNO3 nitric acid
    • HI hydroiodic acid
  4. Strong bases
    • LiOH- lithium hydroxide NaOH sodium hydroxide
    • KOH potassium hydroxide RbOH rubidium hyddroxide
    • CsOH cesium hydroxide Ca(OH)2 calcium hydroxide
    • Sr(OH)2 strontium hydroxide Ba(OH)2 barium hydroxide
  5. Compounds that react with acid to form gas and what gas they form
    • 1. Sulfides H2S 2. Carbonates CO2 3. Bicarbonates CO2 4. Sulfites SO2 5. Bisulfites SO2
    • 6. Cyanides HCN
  6. Compounds that react with base to form gas
    Ammonium salts NH3
  7. Boyle's law
    The volume of a fixed mass of gas is inversely proporiton to the pressure applied to the gas if the temperature is held costant.

  8. Charles Law
    Volume of a fixed mass of gas is directly proportional to its K temperature, if the pressure remains constant.

  9. Gay-Lussac Law
    The temperature of a fixed mass of gas is directly proportional to the pressure if the volume remains constant

  10. Avagadro's law
    when measure at the same temp and pressure equal volumes of gases contain equal numbers of moles of gas. The volume of a gas is directly proportional to its number of moles if temp and pressure are constant.

  11. IDeal gas law
  12. Dalton's law of partial pressure
    The total pressure of a mixture of non-reactive gases is equal to the sum of their individual pressures
