Bought it from a lab supply store. If u are outside india, you can try the websites of popular indian chemical companies such as SRL, Himedia, LobaChemie, SDFCL, CDH, Qualigens, Rankem etc. You can see many Himedia products on amazon. You can also try contacting Fischer chems, Flinn scientific, Sigma (very costly), Merck (German), carolina biological supplies etc if u r based in the US. good luck
Thank you for this clear description. Can you make one for Melzer's reagent: 40 parts (by weight) H2O, 2 parts KI, 1 part iodine, and 40 parts chloral hydrate. And, do you know if the iodine in Melzer's is elemental or can be in a tincture?
How is iodine powder purified? I saw this in a video entitled (Make iodine from tincture of iodine), but I did not understand it enough and the matter needs more details and about the percentage of purity that can be obtained. This is important because if you can purify it, I don't think there is a need to buy high purity iodine, which can be twice the price of impure iodine!.
Peace be upon you, my brother. I make a mixture of floor fresheners. I have no smell left for all the time. What is the equivalent of first lime in water?
hi..........are there Iodine + potassium Iodide sellers that ships to Singapore (at reasonable prices)...........Ebay's USA sellers don't send to Singapore anymore.........and i doubt the safety of Iodine + potassium iodide from China........what if i just use iodine OR potassium iodide alone ?.......or i absolutely need to combine the 2 items ?..............many many thanks in advance !
Iodine will not dissolve in water. It needs potassium iodide ions to dissolve. Having said that, i see no reason why iodine solution will be hard to find in any part of the world. It is a very common school level science lab reagent. Try to contact any local science supply company/store or a friend who works in a school/college/university. They will have it, i bet
@@TheSingtangpaScienceGuy ..............oh yeah, now i remember............i've been making Lugol iodine solution for oral consumption for years...........but now i can't find trusted Ebay sellers.............Amazon only sell potassium iodide crystals so i might have to settle for that without the iodine crystals..........
To prepare %2 - 100 ML Lugol's iodine... Formula : M1.V1 = M2.V2 %5.V1 = %2. 100ML ----> V1 = 40 ML .... 40 ML Lugol's iodine 5% +++ fill up to 100 ML ... So, we get Lugol's iodine 2%, am i right ?

5:45 Lugol's iodine 5% solution preparation
A very understandable explanation. Now anyone can easily prepare a Lugol solution at home. Thanks.
Hi @ThomasTKtungnung, thanks for the video. If the solution is called 5%, shouldn't the water content be 85 ml and not 100 ml?
Is this can work after 10 years of taking levothyroxine, and having Subliclinal Hypothyridism?
hi Sir, thanks for the video.
I have a 0.05 M iodine solution and i want to use it for staining experiment, do I just dilute it with water ?
Thank you for taking the time to make the video. What percentage (%) is the Lugol's solution?
Thanks. Its 5%
thank you very much for this preparation video
Where do you purchase your elemental iodine. It is very hard to find a supplier, not to mention a reputable one.

How can I make Molecular iodine?
(That is superior to regular iodine)
