WebJan 30, 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. WebApr 28, 2024 · Consider the salt formed when the weak acid hydrofluoric acid is neutralized by the strong base sodium hydroxide. The molecular and net ionic equations are shown below.

The surrounding ions are located at the vertices of a regular octahedron. In the language of close-packing, the larger chloride ions (167 pm in size ) are arranged in a cubic array whereas the smaller sodium ions (116 pm ) fill all the cubic gaps (octahedral voids) betwee…
NaCl is a neutral compound as it has a pH value of 7. It is neither acidic nor basic in nature. NaCl is neutral as it is formed by the neutralization reaction of HCl (strong acid) and NaOH (strong base). The strong acid and strong base in the aqueous solution neutralize each other forming a neutral product ie; NaCl … See more A general idea behind the neutrality of sodium chloride is that the acidic, basic or neutral nature of a compound can be told easily by its pH value. Any compound having a pH value lower than 7 will be acidic in nature, … See more When dissolved in water, acids produce hydrogen ions which on combined with water molecules result in the formation of hydronium ions, whilst … See more As NaCl is an inorganic compound, its structure cannot be explained by the rules used to understand the structures of organic compounds. NaCl has a rock salt crystal structure with a face-centered cubic Bravais lattice. … See more The pH of solid NaCl can be calculated easily by dissolving it in water in small quantities.
