✓ Answer: A Sodium chloride (NaCl)
Sodium chloride (NaCl) produces a neutral solution because it is a salt formed from a strong acid (HCl) and a strong base (NaOH). When dissolved in water, the ions of a neutral salt do not react with water (hydrolysis), keeping the pH at approximately 7. If a salt is formed from a strong acid and a weak base, the solution will be acidic; if it's from a weak acid and a strong base, the solution will be basic.
