Hydrochloric acid solution can be standardised by following methods (All volumetric titration methods)

  • Using Sodium carbonte using Methyl red indicator. Factor is each mL of 0.1 M HCl is equivalent to 0.005299 of Sodium carbonate.
  • Using THAM (Tris-hydroxymethyl - amino methane (Tromethamine) using Bromocresol green indicator. Fctor is each mL of 0.1 M Hydrochloric acid solution is equivalent to 121.14 mg of Tromethamine.
  • Using standard Sodium hydroxide solution (phenolphthalein indicator).
    However, for standardisation of volumetric solutions one must use primary standards.
