Throughout the separation process students frequently observe that their sodium hydroxide solution is colored due to hydrolysis of small quantities of acetaminophen by sodium hydroxide to form 4-aminophenol, which is oxidized to a highly colored compound. Define how the separation could allow traces of acetaminophen in the aspirin and caffeine solution. Explain the solubility of CH2Cl2 is acetaminophen 0.0005, aspirin 0.033 caffeine 0.089 g/mL.
