Why starch reacts with lugols solution?
This solution is used as an indicator test for the presence of starches in organic compounds, with which it reacts by turning a dark-blue/black. Elemental iodine solutions like Lugol's will stain starches due to iodine's interaction with the coil structure of the polysaccharide. Starches include the plant starches amylose and amylopectin and glycogen in animal cells. Lugol's solution will not detect simple sugars such as glucose or fructose. In the pathologic condition amyloidosis, amyloid deposits (i.e., deposits that stain like starch, but are not) can be so abundant that affected organs will also stain grossly positive for the Lugol reaction for starch.
What does lugol's iodine?
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.
Differences between lugols iodine and grams 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.
Can you buy potassium iodine over the counter?
Your local pharmacy may have some though there have been reports that they have been told to stockpile.Do a quick google for Bobbys Healthy Shop, they sell Lugols Iodine Solution with a dropper. They also sell a concentrated brand you can dilute yourself. This is the standard treatment for soldiers and members of the armed forces.Lugols Iodine is a combination of elemental iodine and potassium iodide and protects the body from the damaging effects of radiation damageThey also sell Spirulina which is helpful for a radiation detox.http://www.bobbyshealthyshop.net/Lugols-Iodine.phpYou can also find some at VRP, which is the site I use for vitamins. They have Potassium Iodate available. These are capsules with a 5 year shelf life I think.http://www.vrp.com/minerals/potassium-iodate** (though i have seen no information that IODATE is appropriate for radiation prevention and tablets in general are poor in quality... so buyer must do their own research)It is difficult these days to purchase iodine in a pharmacy because anyone who sells iodine must take records of the buyer including name and address due to FDA regulations. There are several companies that sell online. Your information would most likely be recorded when you purchase it that way.CheapIodine.com is a great website for buying Iodine in Bulk.
