  1. Strong and Weak Electrolytes

  2. Strong and Weak Electrolytes • Pure water does not conduct electricity because of a lack of free moving ions.

  3. Strong and Weak Electrolytes • An electrolyte is a substance that, when dissolved in water, produces free moving ions that allows the solution to conduct electricity. Add electrolyte 

  4. Strong and Weak Electrolytes good • Strong electrolytes are ________ conductors of electricity and that ________ electrolytes are poor conductors of electricity. weak Add strong electrolyte Add weak electrolyte

  6. Strong and Weak Electrolytes • These are the strong electrolytes! • Strong acids: HI, HBr, HCl, HNO3, and H2SO4 • Strong bases: LiOH, NaOH, KOH, RbOH, CsOH • Soluble salts: are found using Reference Table F NaCl, MgSO4, K2Cr2O7, NH4NO3, etc!

  7. Strong and Weak Electrolytes • These are the weak electrolytes! • Weak acids: are all acids that are not strong • Weak bases: are all bases that are not strong • Insoluble salts: are found using Reference Table F

  8. Strong and Weak Electrolytes Ex. (1) List the five strong acids that you must know for this course. ________, ________, ________, ________, and ________ Ex. (2) List the five strong bases that you must know for this course. ________, ________, ________, ________, and ________ HCl HBr HI HNO3 H2SO4 LiOH NaOH KOH RbOH CsOH
