Very useful. Thank you. About to have a thyroid scan utilizing radioactive-iodine, and supposed to be on an iodine-free diet for 2 weeks before the test. Not sure about iodine content in salt (even with no mention of iodine by manufacturer), I had to eat salt-free food for 2 weeks the last time I had this test. Salt-free food experience was not that horrible, but was not that pleasant either! This time, with the help of this video, I will be able to test for iodine presence, so I won't have to give up salt again before the test ♥♥
The reaction goes more quickly in acidic medium; therefore vinegar is added to provide a source of acid. If you try the experiment using vinegar instead of water and it works just as well, be sure to let me know this!
Tommy Technetium Well, I suspect I have Hyperthyroidism and every dietary advice about it suggest that I should avoid iodized food, which is impossible today. So can Vitamin C make iodized food easier to process?

Thanks for the video! I want to test different brands of salt and find out which brand has the most iodine. Will the reaction become darker as the content of iodine increases?
Hi Cassidy. My guess is that this will work. However, you might not be able to differentiate precisely between samples that vary just a little bit in the amount of iodide present. When doing this test, be sure to incubate all of your different samples at the same temperature, with the same amount of added peroxide, and for the same amount of time. Let me know how it works out for you.
grate some raw potatoes, mash them when raw, boil the mash with a cup of water until half a cup remains. Filter out the potato shreds. The filtrate (water that came out under the filter) is starch water.
okay, i will try on the three salts i have, i worded my comment poorly though, i meant that salt seems to have very little in it these days, and i was stunned by your results, i did not realize it was ten years ago. the reason i am stunned is because i eat a lot of salt with iodine in it, and recently found i was severely low on iodine.@@TommyTechnetium
That's a good question, mir amir. I think it would depend upon how much of the salt you gave to the fish, and also how the salt was administered to the fish (injected in the body, orally, etc).
Thank you for this. I need a low iodine diet and was concerned my sea salt had iodine. I did a modified version of your experiment with lots of cornstarch both with ionized salt and my sea salt. It worked perfectly!
Michael I did find a kit called multi test iodine and iodide which is used to test marine water and I’m using that to test iodine in Salt that is diluted with water. It can detect small amounts of salt.
Hi, Since iodised salt is not good for aquarium, i would like to do this test to confirm there is no iodine in the salt i bought for my aquarium.. This will help right??
One question, iodised salt has high ppm of iodine. What about pink Himalayan salt. Will one gets deficiency of iodine if consumes only pink salt and not the iodised salt? Ive heard it only has 2ppm vs about 40 in iodised salt. But i leave it to an expert like you.
Iodine is in fish, in large amounts in some seaweed, in eggs when chicken had some iodine in their food. But you may develop iodine deficiency, especially if you are a vegan. You can buy iodine supplements and it is in some multivitamins also.
@@rreddingExactly. Iodine is in sea water, hence in fish / seaweed etc. Iodine is only present in veges or eggs if they have absorbed Iodine . Our topsoil is almost devoid of Iodine now, so usually nothing has it except fish / seaweed / etc.
Table salt is almost 100% sodium chloride. However, various brands of table salt have different additives. Some table salt contains iodide, while other table salt does not.
Hi Sasho. Table salt contains mostly sodium chloride (formula NaCl). It also contains other additives. In some cases, sodium iodide (formula NaI) is added to salt. This is done because iodide is a necessary nutrient. Not all salt contains sodium iodide. Salt that contains sodium iodide is said to be "iodized".
@@sashosubramony914 It is not. In my country, you can buy salt that has printed on the label the following: "this salt does not supply iodide, a necessary nutrient".

very useful demonsration. thanks a lot.
😊😊
Can we just mention how this guy is still responding to comments after uploading this video 7 years ago
Neat work, sir! You care for the environment too!
By the way, what is the harmful effect of Iodine on anything after the drainage system?
Iodine is a fairly good oxidizing agent, and used as a disinfectant
Great explained..
Is corn startch required?
Not at all
i tested it with iodized salt and no result. its may that it just recognises the salt iodized by Potassium iodide not Potassium iodate
What is the imprtance of vineger here?pls explain

I really do appreciate the video, hoping i will pass my science fair project thank you
May God bless you
So does this mean that Vitamin C can neutralize the Iodine in a person with hyperthyroidism?
Good question! The iodine (I2) in the body is in the form of iodide (I-). Therefore, it is already in the "neutralized" form.
Tommy Technetium Well, I suspect I have Hyperthyroidism and every dietary advice about it suggest that I should avoid iodized food, which is impossible today. So can Vitamin C make iodized food easier to process?
@@Lemanic89 I would follow the direction of your medical doctor.
@@TommyTechnetium Lugols Iodine (with Potassium Iodide also) ... perhaps that is affected by Vit C?
Thanks great video! Was the water distilled? Do you think any halogen content in the water might have exacerbated these effects you found?
Thank you for your kind words 😊. Notice that any halogen content in the water would also have shown up in the control (the non-iodized salt), correct?

Hi What strength hydrogen peroxide are you using?
3%
grate demonstration! Thank you. I tryed it with corn starch on a sample of iodized and non iodized salt and it worked.
That's good to know, Daniel. Thank you for your input!
i tried and it didnt work :(

so this is just a more expensive way to create Hydrogen that is released.could it be possibile to condense the released 2H to create liquid hydrogen?
Is there any easier way to achieve this. I mean, that starch is difficult to find commercially
Try adding a little bit of cornstarch. If you try this, let me know if it works!
Can i use rice water as starch?
grate some raw potatoes, mash them when raw, boil the mash with a cup of water until half a cup remains. Filter out the potato shreds. The filtrate (water that came out under the filter) is starch water.
I have a very hard time believing that iodized salt has that much iodine in it.
Try the experiment for yourself and let me know what you see

Thelugu
how to calculate concentration of iodine in salt ?
Try an iodometric titration
if i give iodised salt to a fish what will fish reacts

blue black? isnt iodide red-black? ive thought ive seen it before as a liquid, but i keep reading people say "blue-black" online
The blue-black color comes from the iodine-starch complex formed in the reaction between iodine and starch
You can't pour it down the drain but need it as a supplement.
Hi,
Since iodised salt is not good for aquarium, i would like to do this test to confirm there is no iodine in the salt i bought for my aquarium..
This will help right??
Yes, I think it could work, depending upon what compounds are in aquarium salt. Let me know how your test works out
why did mine turn yellow?
Did you add starch?

I've tasted Iodized salt in chicken soup and it had a very bitter after taste it was like eating poison very bad and nasty taste to it.
Table salt is not always a pleasant taste. Sea salt is nicer
very useful for my project in school
In my home town we used to pronounce "Iodeen" with the 'o' barely pronounced.
In Russian "Master Yoda" sounds just like "The Master of Iodine"
Hi! How could you make this a quantitative test?
You could try using an RGB analyzer app on a smartphone to quantify the degree of dark color developed in each beaker
Wait so is table salt and iodized salt the same
Table salt is almost 100% sodium chloride. However, various brands of table salt have different additives. Some table salt contains iodide, while other table salt does not.
can u tell me the importance of this experiment??
It is a qualitative test for the presence of iodide ion in salt.
This was really informative. Thank you
God Bless
whats the purpose of the expirement
To use a chemical test to demonstrate that iodide is contained in iodized salt.
hi, whats iodated ?

@@TommyTechnetium Thank you for your response. Im trying to find non iodize salt but in my country everywhere it says iodated, is it the same thing ?
@@sashosubramony914 It is not. In my country, you can buy salt that has printed on the label the following: "this salt does not supply iodide, a necessary nutrient".
Hi, can you make similar video for presence of Fluoride? It would be much more useful as the Iodine is harmless. Thanks
not harmless, too much of it is harmful
Iodine isn't harmless if you are allergic to it.
Yes Fluorine is the worst / most amazing / most reactive chemical
Do you have any videos about different types of pink Himalayan rock salt to check if they have any iodine in them at all.
No I don't, but I'll do some experiments on this if I get the time. Thank you for sharing this idea with me!
