Design a simple experiment to distinguish between hydrophilic and hydrophobic substances. You start by adding equal amounts of vinegar and oil to a container. After shaking, the vinegar and oil levels separate, based upon polarity and density. To this you add glucose and sodium citrate and shake again. Where do you expect to find the glucose and sodium citrate in greatest quantities?

Answer:

Vinegar

Explanation:

Both sodium citrate and glucose are polar substances. Since they are polar substances, they will be found in greater concentration in the aqueous phase. The aqueous phase in this case is vinegar.

Hence a greater concentration of the sodium citrate and glucose will be found in the vinegar with only very little concentration in the oil.
