How do you separate iodine and lead sulphate?

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.
