H2SO4 + CH3COONa titration

H2SO4 + CH3COONa titration can be performed. It is because one is strong acid and other one is a weak base. So they can be titrated against to get the endpoint sharply.


Conical flask, pipette, burette, H2SO4 and CH3COONa solution.


Methyl orange is used because we are titrating strong acid and weak base


  • 20 ml of sodium acetate solution is pipetted into a conical flask and burette is filled with H2SO4.
  • Methyl orange indicator is added into the solution in conical flask until it turns into a yellow color.
  • Titrate the solution against sulphuric acid in burette until the color changes from yellow to red color.
  • Note down the burette reading and do the respective calculations.

H2SO4 + CH3COONa net ionic equation
