Titration-finding the concentration of a solution of sulphuric acid

Finding out the accurate concentrain of sulphuric acid Aim The point of this investigation is to find out the concentration of the sulphuric acid in my experiment. I will do this by titrating the sulphuric acid with sodium carbonate. H2SO4 + Na2CO3 à Na2SO4 + H2O + CO2 Acid + Alkali à Salt + Water + Carbon dioxide Ratio of sulphuric acid to sodium carbonate: H2SO4 : Na2CO3 1 : 1 Concentration of sulphuric acid: H2SO4 is approximately 0.05 - 0.15 moldm-3 …

…in the flask and checking the colour. As soon as we got a rough titre, on the real titration we made sure that as soon as we got close to that titre we released the acid in minute amounts. This ensured that the titres were accurate. Each time we did a titration, I washed out the conical flask with a sample of the sodium carbonate to get rid of any of the sodium sulphate formed.
