Lugol's iodine is an organic iodide preparation that helps reduce the vascularity of the thyroid gland prior to definitive surgery for Grave's disease. This is brought about by induction of the Wollf Chaikoff effect caused by the the exogenous iodide which causes suppression of TSH mediated stimulation of the thyroid and helps in its atrophy. But before this can be attempted, the patient must be rendered euthyroid, since the initial effect of iodine could cause aggravation of thyrotoxicosis in an already uncontrolled Grave's disease.
The Lugol solution has a brown color.
Yes, in humans at least. Iodine is an essential element, meaning we must consume it in our diet. We need iodine for our thyroid gland to work properly, but you shouldn't worry about becoming deficient in iodine since in most counties iodine has been added to table salt since the 1920's.
Iodine is a halogen. Single atom has 53 protons.
Tincture of iodine is a mixture of iodine dissolved in a potassium iodide solution. Iodine is the pure compound. At room temperate, iodine is quite unstable and tends to sublime. The tincture of iodine KI3 is used to stabilize iodine in certain experiments and as a reagent.
The iodine anion is iodide. (I^(-)).

Iodine
Lugol's Iodine = 20g Potassium Iodide + 10g Iodine dissolved in 1L H2O Gram's Iodine = 6.7g potassium iodide + 3.3g Iodine dissolved in 1L H2O Recipe's taken from Flinn Scientific Catalog I have on campus. Looks to me as Gram's is just a dilute version of Lugol's. Same ratio of KI:I just less of it. Couldn't tell you much about differences in application however.
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.
Starch
yes and no
intense blue or black
probably because iodine sticks to the oil from your fingers
There is no evidence that it does.
it separates the starch like on photosynthesis.
