What is the primary purpose of using Iodine tablets?

Iodine tablets are primarily used to purify water, which makes them essential in situations where access to clean drinking water is compromised. Iodine works by destroying bacteria, viruses, and some protozoa that can cause waterborne diseases. When added to water, iodine tablets dissolve and release iodine, which then interacts with pathogens in the water to make it safe for consumption. This method of water purification is particularly useful in emergency situations, outdoor activities, and military operations, where maintaining safe drinking water is crucial for health and operational effectiveness.

Other choices, while enticing in their own right, do not align with the primary function of iodine tablets. Flavoring water is not a purpose of iodine tablets, nor do they cool or preserve water. The focus is specifically on their role in eliminating harmful microorganisms to create safe drinking water.
