The active ingredient in a certain toilet cleaner that claims to ‘remove lime scale and rust’ is hydrochloric acid of approximate concentration 1.12 mol/L. To analyze this toilet cleaner, a quality control chemist first delivered a 16.2 mL aliquot of the toilet cleaner into a 250-mL volumetric flask, then made up the diluted solution. She then titrated a 24.8 mL aliquot of this diluted solution against standard sodium hydroxide solution of concentration 0.2178 mol/L. The expected titre (or volume of the titrant) would be approximately:
