What is iodine used for?
Answer:
Iodine is used in pharmaceuticals, antiseptics, medicine, food supplements, dyes, catalysts, halogen lights, photography and water purifying.
purifying water, cleansing cuts.
Iodine is usually used for minor cuts. It stings, but it helps to heal a small cut. Also a lot of the girls when I was younger would use iodine and baby oil together for a quick tan.
I think Iodine is put in salt to prevent goiter. Its a disease of the thyroid gland that happens when you don't have enough iodine in your body. The neck starts to swell up. Iodine can also be used as an indicator in some experiments.
An antiseptic on wounds and stings etc,
Iodine has many many uses. It can be used as a poison if ingested. However, if used topically, it can help to clean out a wound or sore and promote healing. Straight iodine or compounds containing it, such as Betadine (the orange liquid used in hospitals, particularly in surgery) are both examples of this disinfectant property of iodine. Iodine has also been used in creating dyes for cloth and other materials for many centuries.
In the human body, iodine is an essential element we cannot produce and which must come from our diet. Primarily, iodine is required by the thyroid gland so it can produce its various hormones, such as thyroxine and thyroid stimulating hormone (TSH). Without iodine, the thyroid gland, receiving feedback from the pituitary gland that not enough hormones are being produced, will grow larger so there are more cells to produce the necessary products. The continual feedback loop will cause it to continue to over-grow to the point of creating a very large, pendulous gland, which is called a goiter. Such a condition was much more common before iodine was routinely added to commercially produced table salt, and was particularly common in people of Scandinavian descent, whose diet was primarily fish (surprisingly not very high in iodine).
In addition to being required for proper thyroid functioning, iodine is also used in various enzyme molecules in many body systems. Without these enzyme catalysts, many essential digestive and neurological functions would not be able to occur properly.
There are probably industrial uses for iodine about which I do not know, but hopefully your other responders will help there.
