Title: Sulfur
Post by: Scratch- on April 22, 2004, 04:22:34 PM

I tried heating sulfur with iron to produce iron sulfate but the sulfur started burning and making a fowl smelling smoke. Can you think of a way to prevent it from reacting with the air while it combines with the iron?

Put it in your vacuum chamber, and make sure you build it out of sturdy stuff. Like concrete.

I haven't built it yet, just planning.

Sulfur sublimes, therefore vacuum isn't too good of an idea.  Why are you trying to make iron sulfide anyway?

Just... to make it.

Is iron sulfide good for anything? Not that its bad to make stuff for the heck of it, I can definantly understand that, cause thats what I want to do too! Sure you can buy compounds from a chemical store, but its much more gratifying to synthesize stuff yourself. Unless you want a big quantity.

I agree. What I would like to do is make a collection of crystalline salts.

Iron sulfide is insoluble in water and other solvents so it will be difficult to obtain crystals.

What if I melt it and let it slowly reform, like crystals in volcanic rocks.
