Question makes no real sense but the answer is probably 7.
the pH level of sodium chloride (NaCl) is 7.
Sodium chloride doesn't react with water; sodium chloride is dissolved and dissociated in water.
No. Sodium chloride is a neutral salt so if it's dissolved in pure water (pH 7) then the pH won't change (as it doesn't release or take in hydrogen ions)
Evaporating the water sodium chloride is obtained.
it has neither an acidic nor an alkaline pH, it is neutral at pH 7
PH 7 (im not completely sure though) :-) Yes i think it is too, thanks
Crystals of pure sodium chloride are colorless.
Sodium chloride is a compound, not a mixture; after refining NaCl become very pure.
Sodium chloride is very soluble in water at any temperature.
yes because the two atoms that is sodium which is small in size and chlorine which is highly electronegative can form hydrogen bond not only in between themselves but also with solvent (pure water).
Pure saline water is only a solution of sodium chloride in water.
Pure sodium chloride crystals are colorless.
