You prepared standard benzoic acid and caffeine solutions that allowed you to produce four standard curves with the linear equations listed below. You also diluted an unknown solution by taking a 4 mL aliquot with a volumetric pipet and transferring it into a 100 mL volumetric flask that contained 10 mL of 0.10 M HCl. You then diluted it to the mark with Dl water. You measured the absorbance at both wavelengths for the diluted unknown. The data is shown...

Acid/Base Extraction
ACID/BASE EXTRACTION Provide a flow chart detailing the acid/base extraction/separation of the compounds shown below. Your answer must employ the following reagents: methylene chloride, hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M), 10% sodium bicarbonate (aq). Clearly indicate the product(s) and layers formed following each step of your separation scheme. HINT: phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in both sodium hydroxide and...
