Answer: The correct option is b that is the solute is iodine, and the solvent is alcohol and water in an iodine tincture. Iodine tincture is frequently referred to as a dilute iodine solution or iodine tincture and it is used as an antiseptic to disinfect wounds.
Explanation:
- Tincture of iodine is frequently present in emergency survival packs and is used to clean drinking water and disinfect wounds.
- The alcohol-free Lugol's iodine, an aqueous solution of iodine in potassium iodide solution, or alternatively povidone-iodine (brand names Wokadine, Betadine), a PVPI solution, can be used when an alcohol solution is not preferred for this purpose.
- Fruit and vegetable surfaces are sanitized with an iodine solution to remove bacteria and viruses. Iodophor at a concentration of 25 ppm for one minute is the standard for sanitization.
- However, the efficacy depends on whether the solution enters rifts and whether initial dirt removal is successful. Protozoan parasite oocytes won't be destroyed, and bacterial spores are similarly unlikely to be destroyed.
