Plan: How to find the accurate concentration of the Sulphuric Acid. Reaction Sodium Carbonate + Sulphuric Acid Sodium Sulphate + Water + Carbon Dioxide Na2CO3 + H2SO4 Na2SO4 + H2O + CO2 - I have chosen to use Methyl Orange as the indicator for this experiment, this is because Sodium Carbonate Solution is a weak alkali and Sulphuric Acid is a strong acid. Methyl Orange indicator solution works best between a weak alkali and a strong acid, therefore Methyl Orange will work most effectively because it is at its optimum environment between these two solutions. Quantity of Sodium Carbonate to be used Number of moles of Sodium Carbonate = Volume x Concentration Volume in decimetres = Volume / 1000 = 250 /1000 = 0.25 Number of moles = 0.25 x 0.1 = 0.025 Mass of Sodium Carbonate to be used = Number of moles x Molar mass = 0.025 x 106 Mass to be used = 2.65 Apparatus .100cm3 conical...
