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.
Evaporating the water sodium chloride is obtained.
Crystals of pure sodium chloride are colorless.
Sodium chloride is very soluble in water at any temperature.
Sodium chloride is a compound, not a mixture; after refining NaCl become very pure.
Pure saline water is only a solution of sodium chloride in water.
Pure sodium chloride crystals are colorless.

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)
Pure sodium chloride doesn't contain calcium chloride.
