WebMar 14, 2024 · The pH will remain neutral at 7. Halides and alkaline metals dissociate and do not affect the H + as the cation does not alter the H + and the anion does not attract the H + from water. This is why NaCl is a neutral salt. In General: Salts containing halides (except F -) and an alkaline metal (except Be 2+) will dissociate into spectator ions.
