  1. Based on light bulbs and electric currents, how do we know a solution has ions?
    • If the light bulb has a light, it has ions.
    • If the light bulb does not turn on, it has no or very few ions and is deionized.
  2. What are the categories for the amount of electrolytes in a solution?
    • Strong electrolyte: completely dissociates into ions
    • Weak electrolyte: only some dissociate
    • No electrolytes
  3. 1st Solubility Rule
    Li+ Na+ K+ Rb+ Cs+ and NH4salts are soluble
  4. 2nd solubility rule
    • NO3- 
    • C2H3O2- 
    • ClO4- salts are soluble
  5. 3rd Solubility Rule
    Ag+, Pb2+, Hg22+ salts are insoluble.
  6. 4th Solubility Rule
    Cl-, Br-, and I- salts are soluble.
  7. 5th Solubility Rule
    CO32-, S2-, O2-, OH-, PO43-, and Cr2O42- are insoluble except for Ba(OH)2 and Sr(OH)2.
  8. 6th Solubility Rule
