You can add a few drops of starch solution to the yellow liquid. If the liquid turns blue-black, it indicates the presence of iodine. This reaction is due to the formation of a complex between iodine and starch that results in the blue-black color.

Does black salt contain iodine?

Some facts show black salt contains iodine.The fact is,in India some places like Jammu (a province of India).It is used in Jammu to cure goiters.This disease occurs due to lack of Iodine.So,its clear black salt contains IODINE. My dear friends,black salt also cure thyroid. THANKS


NaCl is iodised salt and iodine show sublimation so while cooking is there any iodine present after the the food is cooked?

Iodised salt contains a very small amount of iodine added to prevent iodine deficiency. When heated during cooking, the iodine content in iodised salt does not vaporize or sublimate significantly to create a health concern. Hence, the amount of iodine present in the food after cooking from iodised salt is negligible and safe.


Why do en leaves not turn blue backby iodine?

En leaves do not turn blue-black with iodine because they do not contain starch, which is what iodine reacts with to produce the characteristic color change. Starch is a carbohydrate produced by plants through photosynthesis, so leaves that do not contain starch will not show the blue-black color reaction with iodine.


Which substances show sublimation at atmospheric pressure?

Common substances that exhibit sublimation at atmospheric pressure include carbon dioxide (dry ice) and iodine. These substances transition directly from solid to gas phase without passing through the liquid phase under normal atmospheric conditions.


Why would hydrolysed starch test negative in iodine testing?

Hydrolysed starch would test negative in iodine testing because hydrolysis breaks down the starch into smaller sugar molecules like glucose, which no longer have the characteristic branching structure of starch that allows iodine to bind and form a blue-black complex. Therefore, with hydrolysed starch, there would be no starch molecules left to react with iodine and show a color change.

Would captain blast herbal e liquid show in pee test?

Captain Blast herbal e-liquid may contain various substances, and whether it shows up on a urine test depends on its specific ingredients. If the e-liquid contains nicotine or other detectable compounds, it may be identifiable in a urine test. However, if it contains only herbal ingredients without any controlled substances, it is less likely to show up. Always check the product's contents for clarity on what may be tested.


Will lodine show up on a drug test?

You get iodine naturally in foods and salt. It is not illegal so they won't test for it. However, iodine is easily detected on toxicology screenings.
