Questions & Answers

Q: Why is iodine used in treating cuts and grazes?

Iodine has strong antiseptic properties, making it effective in preventing infections and promoting faster healing of cuts and grazes. Its violet-colored solution is commonly used for this purpose.

Q: What role does iodine play in thyroid function?

Iodine is essential for the production of thyroid hormones, which are responsible for regulating metabolism, growth, and development. Without iodine, thyroid function is impaired, leading to various health issues.

Q: How is iodine used for water purification?

Iodine can be used to purify water contaminated with waterborne bacteria. A couple of iodine crystals added to the contaminated water neutralize the bacteria, making the water safer for consumption.

Q: Why were iodine tablets given to children after nuclear incidents?

After nuclear incidents like Chernobyl or the one in the UK in 1957, children were given iodine tablets to prevent their bodies from absorbing radioactive iodine from the environment. This helps protect the thyroid from potential damage.

Summary & Key Takeaways

• Iodine is a solid element that is commonly used in a violet-colored solution for treating cuts and grazes due to its strong antiseptic properties.

• It is essential for proper thyroid function and was historically added to table salt in areas with iodine deficiency, preventing diseases like goiter.

• Iodine is also utilized for water purification, as a few crystals of iodine can neutralize bacteria and make the water safer to drink.
