How Much Acid there is in a Solution Analysing Evidence and drawing conclusions This is the reaction between the sodium carbonate solution and the sulphuric acid: H2SO4 (aq) + Na2CO3 (aq) Na2SO4 (aq) + CO2 (g) + H2O (l) From this equation it is clear to see that one mole of sulphuric acid (H2SO4) reacts with one mole of sodium carbonate (Na2CO3), to produce a neutral salt sodium sulphate (Na2SO4), carbon dioxide (CO2) and water (H2O). Firstly, I am going to calculate the concentration of the sodium carbonate that was used. This is done by using the formulas: Number of moles (in mol) = mass (g) ÷ relative formula mass (g) So the concentration is equal to: concentration (in mol dm-3) = Number of moles (in mol) ÷ volume (in dm3) When working out the concentration of the sulphuric acid, it is immediately clear that it has the same number of moles as the sodium carbonate solution, as...
