Iodine (I2) is often used by backpackers and travelers for the treatment of drinking water. However,...
Iodine (I2) is often used by backpackers and travelers for the treatment of drinking water. However, many people find the taste of iodine offensive. As a result, vitamin C, a.k.a. ascorbic acid (C6H8O6), tablets are sold as a “neutralizer,” that can be added after water treatment to remove the iodine taste and color. The products of the reaction are iodide ions and dehydroascorbic acid (C6H6O6). Zinc metal could be used instead of Vitamin C to remove the iodine. This fact...
