... Titration AIM: The aim is to find the accurate concentration of sulphuric acid H2SO4 using titration with anhydrous sodium carbonate Na2CO3 The following equation shows reaction (neutralisation) between sulphuric (VI) acid and sodium carbonate solution: Na2CO3 (aq) + H2SO4 (aq) Na2SO4 (aq) + CO2 (g) + H2O (l) This equation shows that one mole of sodium carbonate reacts with one mole of sulphuric (VI) acid. Therefore, they will always have the same number of moles when reacting with each other. We must follow the following steps to find the concentration of sulphuric acid: * We need to find the number of moles of sodium carbonate. We use the following formula to find the number of moles: Number of moles = the mass in gram/the molar mass = the mass/(23 X 2) + 12 + (3 X 16) this tells us the number of moles of sulphuric acid needed for the reaction Number of moles of sulphuric
