5 step method

• 1. list all species present

  • aq = water; list H2O
  • SA = list H+ and conj. anion
  • "in acid" = H+
  • "basic solution" = list OH-
  • List soluble salts as ions (dissociated)
  • insoluble: list as solids
• 2. classify/label entities present as OA and RA

  • Some are both OA and RA (ie. H2O)
• 3. Select the strongest OA and RA

  • transitional metals - consider combinations of substances
• 4. write out half rxn as written in DATA BOOKLET

  • 1/2 rxn for the SRA needs to be reversed
• 5. balance the number of electrons and check charges
• 6. add half rxns togeather; cancel entities and predict if spon or non-spon
