Final answer:
The solubility of morphine in water is 8.8 × 10^-5 M. Morphine's solubility is tied to its chemical structure, which includes two hydroxyl groups important for its activity as a pain reliever.
Step-by-step explanation:
The solubility of morphine, a narcotic pain relief substance, in water is 8.8 × 10-5 M. Morphine is derived from the opium poppy and is the major analgesic in the plant's extract. It features two hydroxyl functional groups that characterize its chemical structure. Small changes in the morphine molecule can lead to different substances such as codeine, used for less severe pain and as a cough suppressant, and heroin, which is a powerful and addictive drug synthesized by chemically modifying morphine.
