Lead(II) fluoride (PbF2) is a chemical compound that is an odorless white solid.
Conditions/substances to avoid are: strong oxidizers.
Lead(II) fluoride is used:
Lead(II) fluoride can be prepared by several methods. It is obtained by treating lead(II) hydroxide or lead(II) carbonate with hydrofluoric acid, followed by evaporation of the solution:
Alternatively, it is precipitated by adding hydrofluoric acid to a lead(II) salt solution, or by adding potassium fluoride to a lead(II) nitrate solution.
