Normality

• Equivalent: material providing 1 mole of “reacting units”:

  • acids/bases: hydrogen ions1 M H2SO4 = 2 N H2SO4
  • redox reactants: electronsin reaction SnCl2 + Cl2 = SnCl4, 1 M SnCl2 is 2 N SnCl2
  • precipitation/complexation: metal chargein reaction BaCl2 + H2SO4 = BaSO4 + 2HCl,1 M BaCl2 is 2 N BaCl2
