A 10 mL of a standard sodium carbonate solution, concentration 0.025 mol L1, is pipetted into a flask. This sample is titrated with hydrochloric acid of an unknown concentration. The ndicator showed that the end-point had been reached when an average titre of 12.35 mL of hydrochloric acid had been added. Na2CO3(aq) + 2HCI (aq) 2NACI(aq) + H20(1) + CO2(g) Calculate the concentration of hydrochloric acid. Show working for full credit.
