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, an antiseptic solution, comprises 2-3% iodine in an alcohol-water blend. Alcohol serves as a carrier, improving iodine's antimicrobial penetration. Elimination of other options:
Iodoform (\( \text{CHI}_3 \)): An antiseptic yellow crystalline compound, distinct from tincture.
2-Iodopropane and Iodobenzene: Organic iodides utilized in chemical reactions, not antiseptic solutions.
Therefore, tincture of iodine is accurately described as "2-3% iodine solution in alcohol-water."
Final Answer: \[ \boxed{\text{2-3\% iodine solution in alcohol-water}} \]
