- 5. A student does a titration using sodium carbonate solution and nitric acid. The equation for the reaction is: Na_(2)CO_(3)+2HNO_(3)arrow 2NaNO_(3)+CO_(2)+H_(2)O 25.0cm^3 of 0.124mol/dm^3 sodium carbonate solution is neutralised by 23.6cm^3 of nitric acid. Calculate the concentration of the nitric acid. Give your answer to 3 significant figures. You should calculate: the number of moles of sodium carbonate in 25.0cm^3 of the solution the number of moles of nitric acid in 23.6cm^3 of the nitric acid the concentration of the nitric acid in mol/dm^3
