Background theory
Equipment used in the experiment: Burette, pipette, pipette filler, clamp and stand, a small and a large beaker, three conical flasks, white paper, phenolphthalein indictor, dilute solutions of HCl and H2SO4 of unknown molarities, and 0.10 dm–3 NaOH.
Equations, diagrams, and calculations:
Concentration of the sulphuric acid solution Molarity of the alkaline solution of NaOH 0.10 mol. dm–3 As found in the experiment, Average volume of H2SO4 is 11.15 cm3 = 0.01115 dm3 H2SO4 → H2+ + SO4– NaOH →Na++ OH– H2+ + SO4–+ 2Na + 2OH → Na2+ + SO4–+ 2H2 O Thus, the hydrogen ions in H2SO4 reacted with hydroxide ions ...
