QUESTION 5 A student investigаtes the reаctiоn between sоdium hydrоxide solution аnd dilute sulfuric acid. He does a titration to find the concentration of the sulfuric acid. This is his plan for the titration. There are some mistakes and omissions in his plan. rinse a conical flask with the sodium hydroxide solution use a measuring cylinder to measure out 25 cm3 of the sodium hydroxide solution and add it to the conical flask add a few drops of phenolphthalein indicator to the conical flask rinse a burette with water and then fill it with the sulfuric acid add the acid from the burette to the conical flask until the indicator changes colour at the end-point of the titration record the final burette reading a Give the colour change of the phenolphthalein indicator at the end-point. from ............................ to ................................. (2) b Describe four changes that the student could make to improve his plan. 1. 2. 3. 4. (4) c The student then does the titration correctly. He finds that 16.70 cm3 of the dilute sulfuric acid neutralises 25.0 cm3 of sodium hydroxide solution of concentration 0.200 mol/dm3 The equation for the reaction is 2NaOH + H2SO4 → Na2SO4 + 2H2O Calculate the concentration, in mol/dm3, of the sulfuric acid. concentration of sulfuric acid = ........................................................... mol/dm3 (3) [9]
