can you check this for me? Thanks! QUESTION You are instructed to add a boiling stone to your conical vial. Choose the statement that best explains why a boiling stone is necessary O The boiling stone prevents the solution from bumping by distributing O The boiling stone allows the solution to be mibxed uniformly during O The boiling stone allows for the distillation to proceed more quickly O The boiling stone prevents the solution from heating uniformly during the heat evenly. the distilation. using less heat the distillation. Choose the piece of glassware that represents a Hickman still. QUESTION 2 peies In a distillation, it is essential to have your thermometer properly placed. Choose the statement that best explains the outcome if the thermometer is placed too low in the Hickman still. O The measured boiling point is too high. O The measured boiling point is too low O The gas will be trapped in conical vial and will not condense in the still O This placement will have no effect on the result 2 peines In the procedure, you are reminded to make sure that your ground glass joint is sealed tightly using vacuum grease. Choose the statement that explains this requirement. O Sealed ground glass joints prevent the gas vapors from escaping the O Sealed ground glass joints help to stabilize the apparatus. O Sealed ground glass joints prevent air from getting in and O Sealed ground glass joints help with even distribution of heat resulting in a faster distillation

Explanation / Answer

Question 1:

The correct answer is Option A

Since the addition of boiling stone will lead to prevent the solution from coming out of the flask and will help in not slipping the liquid, i.e. resistive to the bumps

You have marked it correctly

Question 2:

The hickman still has two openings not one, hence the correct answer must be option B

You have marked it incorrectly

Question 3:

At the time of distillation, placement of thermometer is crucial, if you place it too low, then the effective boiling point will be increase for the vapor gas

Hence the measured boiling point will be too high

Correct answer is Option A

you have marked Option A

Question 4:

The correct answer is Option C since sand and methanol can easily be filtered out using the process of simple distillation whereas other compound must required complex methods to filter out from each other
