Question

Tincture of iodine is the common name for:

• A. \( \text{Iodoform} \)
• B. \( 2\text{-iodopropane} \)
• C. \( 2\text{-3\% iodine solution in alcohol-water} \)
• D. \( \text{Iodobenzene} \)

Hint:

Tincture of iodine combines the antimicrobial power of iodine with the solubility and quick-drying properties of alcohol, making it ideal for disinfecting wounds.

Answer 1

The Correct Option is C

Tincture of iodine is a commonly used antiseptic solution consisting of 2-3\% iodine dissolved in a mixture of alcohol and water. The alcohol acts as a carrier, enhancing the penetration of iodine, which provides the antimicrobial action. Elimination of other options:
Iodoform (\( \text{CHI}_3 \)): A yellow crystalline compound with antiseptic properties but not related to tincture.
2-Iodopropane and Iodobenzene: These are organic iodides used in various chemical reactions but are not antiseptic solutions.
Hence, the correct description of tincture of iodine is "2-3\% iodine solution in alcohol-water."
Final Answer: \[ \boxed{\text{2-3\% iodine solution in alcohol-water}} \]
