How to make ironiii iodide in preferably aqueous solution?
« on: April 01, 2019, 11:37:18 PM »
I would like to have an aqueous solution of dissolved ironiii, Iodide and ironii. However, ironiii iodide is said to "not exist" in aqueous solution or at least to not be stable.

Reason being, iodine is a strong reducing agent and ironiii is a strong oxidizing agent. So you would get something like this in aqueous solution:

Fe3+(aq) + I-(aq) -> Fe2+(aq) + 1/2 I2 (g)

Any ideas on how to keep the ironiii and iodide in aqueous solution without promoting the redox reaction?

Not possible in aqueous solution. Check how normally iron -III-iodide will be made.
