Chromium(III) oxide reaction with HCI.
« on: December 22, 2016, 12:06:00 PM »
What is the reaction of Chromium(III) oxide and Strong Hydrochloric Acid at room temperature? I am trying to produce Chromium(III) Chloride.

More or less what one could expect, but very slow.

Thanks, I guess I can always heat up the solution so it reacts faster.

Relatively fast you can solubilize Cr2O3 by reaction in melting NaOH. The you can neutralize with HCl.
