Finding out the accurate concentrain of sulfuric acid adopt The point of this investigation is to bob up out the density 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 sodium carbonate: H2SO4 : Na2CO3 1 : 1 niggardliness of sulphuric acid: H2SO4 is more or less 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 leave alone apply 2.650g of Na2CO3 in 250cm3 of distilled urine.
