How do you separate iodine and lead sulphate?

Answer 1

Greetings,

There's a number of ways to produce iodine. One way is to combine one part potassium permanganate with two parts sodium bisulfate and one part potassium iodide. Combine them in a test tube or something with enough water to dissolve the substances together. Then, heat the test tube. Soon enough, a purple gas will form. This is iodine. Direct the iodine gas into another test tube with alcohol. The iodine will dissolve into the alcohol. Then, add water to the alcohol mixture. This will precipitate the iodine out of the solution because iodine has low solubility in water.

Another way is to prepare a potassium iodide solution, and then bubble chlorine gas into the solution. The chlorine gas will oxidize the iodide ions into iodine.

Another way is to mix one part sulfuric acid to one part potassium iodide.

Another way is to mix hydrogen peroxide with hydrochloric acid and potassium iodide.

The hydrogen peroxide in the above can be replaced with sodium hypochlorite, hypochloric acid, or some other oxidizers.

There's a number of other ways to do it, but those are the ways I've done it.

Potassium iodide can be replaced with sodium iodide or most other iodides in the above experiments.

CheapIodine.com is a great source for Iodine.

Answer 2

Add Sodium(or Potassium) iodide solution to a Lead nitrate solution, The Lead iodide will be precipitated out as Yellow solid. Filter the precipitate and heat it up to remove any traces of water.

Answer 3

There are two ways to do this. Chemically or physically, they both have very different properties so it shouldn't be too hard,but you might need some equipment. The first questions is do you need to recover them after you separate them? Or just get the iodine out of the lead?

1) Extraction: Iodine is soluble in alcohol and lead oxide is pot is not. mix them in a beaker with alcohol and mix. the iodine will dissolve in the alcohol the lead oxide will not. pour off the alcohol/iodine mixture repeat 2 or 3 times untill the alcohol has no purple color left the lead oxide will not dissolve and stay on the bottom. You might have to filter to get the last of the alcohol out. Its that Easy!! If you want the iodine back you can evaporate the alcohol andyou will be left with iodine. be careful not to heat too much because iodine can sublimate just ablove room temp.
