The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Statement**: The statement to evaluate is "Iodine is used as an antiseptic." We need to determine if this statement is true or false. 2. **Definition of Antiseptic**: An antiseptic is a substance that prevents the growth of disease-causing microorganisms. It is commonly used in medical settings to disinfect skin and wounds. 3. **Properties of Iodine**: Iodine, particularly in the form of tincture, is known for its antimicrobial properties. It can kill bacteria, fungi, and viruses, making it effective for disinfection. 4. **Tincture of Iodine**: Tincture of iodine is a solution that typically contains 2-7% elemental iodine (I2) combined with potassium iodide or sodium iodide, dissolved in ethanol and water. This formulation enhances its antiseptic properties. 5. **Mechanism of Action**: Iodine works by iodinating (adding iodine to) and oxidizing the protoplasm of microbes. This process disrupts their cellular functions, leading to the death of the pathogens. 6. **Conclusion**: Since iodine is indeed used as an antiseptic, particularly in medical settings for pre and post-operative care, the statement "Iodine is used as an antiseptic" is true. **Final Answer**: True ---
