When common salt is added to water does the pH increases or decreases?
Answer:
stays the same. Na+ is a strong conjugate acid and Cl- is a strong conjugate base. salt hydrolysis occurs to the same extent
I would think it would stay the same since the byproduct of mixing an acid with a base is a salt and water.
(e.g. Hydrochloric acid + sodium oxide = Sodium Chloride + Hydrogen Dioxide or Table Salt and Water)
Since it is a salt, not an acidic one, nor is a basic one, I suppose it does not change in pH.
If it does, it may be quite minimal.
Since after all, it is a salt, and most salts are neutral.
