Production of AgF2
« on: 18/12/2004 00:52:33 »
A simple question here, would reaction of elemental silver, or silver chloride, or maybe AgNO3 with aqueous HF produce AgF2?

Or is it nessesscary to actually react silver metal with elemental fluorine? as I am looking for an easy way to store fluorine, AgF2 looks like the best, as the xenon fluorides would be expensive to prepare. Also, can anyone tell me offhand the decomposition temperature of AgF2?

Thanks:)

Wouldn't the product be AgF anyway, rather than AgF2 ? Silver is 1 +

I don't know off the top of my head if AgF has a reasonably solubility or not...check the CRC handbook and if it is not very soluble (Ksp lower than 10^6) then find a fluoride salt to react with, say, silver nitrate and then collect the precipitate.

If AgF IS reasonably soluble, then find an anion to pair with silver that makes a soluble salt and add a fluoride salt whose cation has low solubility when paired with the anion of the silver salt.
