- Brian forgot to close the end of his capillary tube when he was conducting the boiling point determination experiment. He then decided to use a lighter to close the end, making sure that it does not touch the oil. Which of the following statements is true? a. Brian did a great job in making sure that the experiment worked. It is important to close the end of the capillary tube for accurate determination of the lower limit of the sample's boiling point. b. What Brian did is dangerous as oil is a flammable substance. He should have stopped the experiment then closed the tube first before continuing. c. It is not important to close the end of the tube. He could have just proceeded with the experiment or covered the end of the tube with tape since prolonged air contact might contaminate the sample. d. Brian could have covered the end of the capillary tube with his finger, since it is not as dangerous as using the lighter on a flammable substance such as oil.…This is the worksheet and follows the instructions to answer them correctly.If a non-polar mobile phase is used in a non-polar stationary phase, the polar components in a sample will elute first.
