Praseodymium(III) fluoride is an inorganic compound with the formula PrF₃, being the most stable fluoride of praseodymium.

Production

The reaction between praseodymium(III) nitrate and sodium fluoride will produce prasodymium(III) fluoride as a green crystalline solid:[3]

Pr(NO₃)₃ + 3 NaF → 3 NaNO₃ + PrF₃

gollark: I would make it as ridiculous as possible while still having it work.

gollark: Dogecoin is basically Litecoin. If I were to ironically make one, it would be technologically ironic too, somehow.

gollark: Please, I would only make a cryptocurrency *ironically*.

gollark: Troubling.

gollark: You could check an online dictionary.
