2.5 g sample of impure mercury (II) oxide, in excess of potassium iodide is being resolved. HgO(k) +4I^- + H2O ------>> Hg(l4)^-2+ 2OH^- Calculate the percentage of HgO in the sample, since 45 mL of 0.2 M HCl is consumed in the titration of the hydroxide formed. (MaHgO=216.59g/mol)
The active ingredient in a certain toilet cleaner that claims to ‘remove lime scale and rust’ is hydrochloric acid of approximate concentration 11.6 mol/L. To analyze this toilet cleaner, a quality control chemist first delivered a 10-mL aliquot of the toilet cleaner into a 250-mL volumetric flask, then made up the diluted solution. She then titrated a 27 mL aliquot of this diluted solution against standard sodium hydroxide solution of concentration 0.1705 mol/L. The expected titre (or volume of the titrant in mL) would be approximately:
