Titration-finding the concentration of a solution of sulphuric acid

Finding out the accurate concentrain of sulfuric acid determination The point of this investigation is to bob up out the compactness of the sulphuric acid in my experiment. I ordain do this by titrating the sulphuric acid with atomic number 11 change. H2SO4 + Na2CO3 à Na2SO4 + H2O + CO2 Acid + Alkali à Salt + pissing + Carbon dioxide Ratio of sulphuric acid to atomic number 11 change: H2SO4 : Na2CO3 1 : 1 soaking up of sulphuric acid: H2SO4 is intimately 0.05 - 0.15 moldm-3 The average concentration of the sulphuric acid is: 0.05 + 0.15 = 0.1 moldm-3 2 Concentration (moldm-3) = concentration (g dm-3) Molar clutch (g mol-1) Mr of Na2CO3 = (23 x 2) + ( 16 x 3) = 106 g mol-1 250cm3 x 0.1moldm-3 x 106 gmol-1 = 2.650g 1000cm3 I impart routine 2.650g of Na2CO3 in 250cm3 of distilled urine.
