2. After dissolving the KHP with water, a student noticed some undissolved solid, but continued with thetitration as instructed by the procedure. He titrated until the pink color persisted for 30 sec and recordedthe volume of titrant required. Preparing for the second determination, he set the reaction solution asideand added some more NaOH to the buret. He was about to pour the reaction solution down the drain, so hecould rinse and reuse the flask, when he saw that the pink color had disappeared!a) What happened?b) What can the student do to correct for this erTor and salvage this trial? How should the data sheet bemodified to reflect this correction?3. Another student began adding titrant to the acid solution, but stopped when she suddenly realized thatshe forgot to add the 3 drops of phenolphthalein. When she did, the solution immediately turned dark red!a) What happened?b) What can the student do to correct for this error and salvage this trial? How should the data sheet bemodified to reflect this correction?
