Question

PROMPT: Write down as many correct, distinct, and relevant facts you can about: 150 mg of isoleucine C4H10(C)NH2COOH is dissolved in 500 mL of water and extracted with 200 mL of a hydrocarbon mixture. The density of the hydrocarbon mixture is 0.80 g/mL. After allowing for mixing and equilibration, 85 mg of C6H13NO2 is found in the hydrocarbon mixture 5 statements are required for full credit. *** Each statement that you provide must be distinct, correct and relevant in order to receive credit: *Distinct requires that each statement must be different than each of your other statements and the chemical situation described above; the rephrasing of the given information or the statements that you have provided will not count. *Correct requires that each statement is factually accurate. *Relevant requires that each statement is relevant to the chemical situation and to content covered in this course or your prior chemistry courses. Listing facts unrelated to the chemical situation (e.g. “Water is miscible with ethanol”) or listing facts unrelated to course content (e.g. “hexanes are made up of five isomers.") will not count for credit. ***

Answer 1

Some correct facts of the above process can be given as follows :

1. Isoleucine is more soluble in the hydrocarbon mixture than in water.
2. More amount of Isoleucine can be extracted by using more volume of the hydrocarbon mixture.
3. More amount of Isoleucine can be extracted by carrying multiple extractions using small volume fractions of the hydrocarbon mixture than a single extraction with large volume of the hydrocarbon mixture.
4. During the extraction process, the hydrocarbon mixture will form the top layer while the water will form the bottom layer.
5. Isoleucine has a greater non polar character than polar character due to which it is more attracted to the hydrocarbon mixture than to water molecules.
