  • formation of solids
  • pH change
  • temperature change
  • rxn of known acid/base pairs


 

  • involves transfer of electrons
  • involves changes in oxidation states
  • reactions with O2, H2, or other known oxidizers or reducers
  • complexes often colored 
  • reaction of a transition metal with a ligand
