The correct Answer is:
To determine the correct statements regarding antiseptics and disinfectants, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement (i): Antiseptics are chemical substances which prevent the growth of microorganisms.** - Antiseptics are indeed chemical substances that prevent the growth of microorganisms and may even kill them. They are safe to apply on living tissues, such as wounds and cuts. - **Conclusion:** This statement is **correct**. 2. **Statement (ii): Boric acid in dilute aqueous solution is a weak antiseptic for eyes.** - Boric acid, when diluted in an aqueous solution, acts as a mild antiseptic and is commonly used for eye washes. It is also found in some antiseptic baby powders. - **Conclusion:** This statement is **correct**. 3. **Statement (iii): 0.2 percent solution of phenol is disinfectant.** - Disinfectants are substances that kill microorganisms but are not safe for application on living tissues. A 0.2% solution of phenol is actually considered an antiseptic, while a 1% solution of phenol is classified as a disinfectant. - **Conclusion:** This statement is **incorrect**. 4. **Statement (iv): Iodine is a powerful antiseptic.** - Iodine is recognized as a powerful antiseptic and is often used in the form of tincture of iodine for disinfecting skin before surgeries. It is effective against a wide range of pathogens. - **Conclusion:** This statement is **correct**. ### Final Assessment: The correct statements are: - Statement (i) is correct. - Statement (ii) is correct. - Statement (iii) is incorrect. - Statement (iv) is correct.
