Solve 3 and 4 ExperimD. Post Laboratory Questions:1) A student weighs 0.347 g of KHP on a laboratory balance. The KHP was titratedwith NaOH and the concentration of the NaOH determined to be 0.110 M. Forthe second titration, the student correctly diluted 6 M HCI from the reagent shelfusing a graduated cylinder to obtain approximately 0.6 M HCI. This solutionwas titrated with the original NaOH solution. The student calculated theconcentration of NaOH from the experiment to be 0.099 M. In which experimentshould the student be more confident of the concentration of the NaOH solution?Why?2) A student needed to standardize a solution of NaOH which was approximately0.04 M. The student weighed out 0.237 g of KHP. The student carefully preparedthe titration setup, but after 25 mL of NaOH was added, no observable changehad taken place. What is the procedural error in this experiment?3) What is the effect on the determination of the sodium hydroxide concentration(high, low, no effect)a) If the KHP that was weighed was not completely transferred to the volumetricflask?b) If the KHP sample in this experiment was dissolved in 50 mL of water insteadof 30 mL of water.4) A 0.261 g sample of oxalic acid (diprotic acid) required 17.5 mL of sodiumhydroxide solution for complete reaction. Write the equation for this reactionand determine the molar concentration of the sodium hydroxide solution?
