Solution
Chemistry ma’am · 4 steps
Chloroxylenol plus terpineol is Dettol, and you put Dettol on a cut, so it is an antiseptic.
- Name the mixture. The mixture of chloroxylenol and terpineol is sold as Dettol. Chloroxylenol kills the microbes, and terpineol is the second component of the mixture.
- Antiseptic or disinfectant. Both kill or stop the growth of microorganisms. An antiseptic is safe on living tissue such as wounds, cuts and skin. A disinfectant is used only on non-living things such as floors, drains and instruments, because it would harm tissue.
- Where Dettol belongs. Dettol is applied to wounds and skin, so it is classified as an antiseptic. Other textbook antiseptics are bithionol in soaps, iodoform, and tincture of iodine.
- So. The mixture of chloroxylenol and terpineol is an antiseptic, option (a).
The idea to keep. Antiseptic versus disinfectant depends on where it is used: living tissue or non-living surfaces. Remember Dettol as chloroxylenol plus terpineol, an antiseptic.
