The aqueous solution of which salt NaCl or NH4Cl will have high pH?
1. Sodium chloride salt
The salt Sodium chloride is an example of a neutral salt since its aqueous solution forms a solution of pH of 7.
It is formed by the combination of the strong acid Hydrochloric acid (HCl) and a strong base, Sodium hydroxide (NaOH).
2. Ammonium chloride
The salt Ammonium chloride is an example of acidic salt whose solution has a pH of less than seven.
The salt made from a strong acid and a weak base will have a pH of less than seven.
Ammonium chloride is a salt of a strong acid, namely Hydrochloric acid, and a weak base, namely Ammonium hydroxide.
Therefore, Ammonium chloride will have a pH of less than 7.
Hence, the aqueous solution of NaCl will have a higher pH.
