Does iodine react in hydrochloric acid solution?
Iodine will will not react with hydroelectric acid
How do you prepare Wijs solution from iodine monochloride vial for determining the iodine value of a fatty acid?
Wijs solution is iodine monochloride (ICl) dissolved in acetic acid.For a detailed recipe see this link.
What is wijs solution?
Wijs solution is a solution of containing iodochloride in glacial acetic acid. It is used as a mixture to test material (fats, oils or emulsions) for idodine value or iodine number or the ability of material to absorb iodine. often this is calculated by running a blank and a sample with same amount of wijs solution and doing a back titration often with sodium thiosulfate with known normality or molarity. question for others if iodobromide in glacial acetic acid is also known as wijs solution since that is the material i used most often to test iodine value.
How do you know that the ascorbic acid is gone from the solution as you are adding iodine?
When the iodine turns from brown to blue/black. We did this experiment in school a couple of months ago
How is iodine estimated in ccl4 and h2o layer?
Titrate each solution separately with solution of known concentration of sodium thiosulphate. The titre value will give the amount of thiosulphate reacted with iodine, hence you can find concentration of iodine.

What does 12.69 stand for in iodine value calculation?
It is the grams of iodine in a 0.1moldm^-3 solution of iodine
What Is the pH value of hydrochlorlic acid?
The pH value of an acid solution depends on its concentration and the temperature of the solution.
How do you prepare wijs solution?
Iodine monochloride is soluble in alcohol, ether, acetic acid. ICl is prepared from iodine and chlorine.

Is iodine solution ionic?
A solution of iodine is covalent.
What is the difference between iodine crystals and iodine solution?
Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
What chemical test is performed to indicate the completion of the hydrolysis of starch by acid?
If using acid-catalyzed hydrolysis of starch you can tell the hydrolysis is complete with the solution no longer gives a bluish/purple color with iodine solution. The color should be colorless.
What is the solution of tincture of iodine?
iodine
