  2. Lead(II) fluoride - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_fluoride

    Lead(II) fluoride can be prepared by treating lead(II) hydroxide or lead(II) carbonate with hydrofluoric acid: [3]. Pb(OH) 2 + 2 HF → PbF 2 + 2 H 2 O Alternatively, it is precipitated by adding hydrofluoric acid to a lead(II) salt solution, or by adding a fluoride salt to a lead salt, such as potassium fluoride to a lead(II) nitrate solution, [4]

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. For relatively simple ...
