Step by step
Solved in 2 steps
- Techniques that can be used to monitor the extent of the reaction of reflux.Explain the fuctions of each part of the reflux set-upAn overachieving student determines that their neutral liquid unknown contains impurities. Suggest at least one method that could be used to further purify the liquid compound.
- In recrystallization, fluted filter paper is used instead of a regular cone because it minimizes its contact with the glass funnel. Why is this important?In vacuum filtration, the filter paper should be wet before the final product solution is poured into the buchner funnel. Explain why such an action should be implemented.What are the advantages and disadvantages of liquid-liquid extraction method?
- What properties should ideally be possessed by a recrystallization solvent?Name three (3) other types of samples that can be analyzed in a typical acidimetric process.ExplainWhy do we need to clamp the rubber tube when we are transferring the flask from theboiling water to the cool water? Explain how this will affect your results.
