Title: Molten NaCl and Mercury
Post by: samblip26 on October 11, 2020, 03:34:32 AM
I've been looking for information on this subject online and have had little luck.

Anyways, I know that liquid mercury won't react with solid NaCl, but I read in a couple reports that molten LiCl and KCl will react with liquid mercury to form Li(s)/K(s) and Hg2Cl2. I was wondering if anybody had some information on whether this accurate and could be applied to reacting molten NaCl and liquid Hg.

Thanks for your time!

Where did you read it. Mercury is a noble element will not exchange  with alkaline metals.

High stability of Hg2Cl2 can be a factor here, but I agree that it is a rather extraordinary claim that needs a reliable source.

In the given Link it states in the sodiumchloride part, that there is no reaction. The mercury is physically dissolved in the liquid NaCl.

On the other hand Lithium do a reaction.

This is the report that I found. It was published by Emory University, but I haven't anything else supporting its findings.
