I need four methods of standardization of hydrochloric acid and compare each of the four methods for their advantages and disadvantages
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.
