Which statement correctly describes water-soluble chemicals?

• A. Water-soluble dissolve in water and are excreted in urine
• B. Water-soluble accumulate in tissues
• C. Water-soluble persist in environment
• D. Water-soluble are never excreted

Answer: (A)

Water-soluble chemicals are hydrophilic, meaning they dissolve in water and move freely in the body's aqueous compartments. The kidneys filter blood to form urine, so these compounds are typically eliminated through urine, especially after metabolic steps like conjugation that increase their polarity. This makes them less prone to long-term tissue storage compared with fat-soluble substances that tend to accumulate in fatty tissues. Environmental persistence is not determined solely by solubility, and many water-soluble chemicals are indeed excreted rather than staying in the body.
