True or False: A solution made from NaCl and HCl will act as a buffer solution

This statement is false.

A buffer solution is designed to resist changes in pH upon the addition of small amounts of an acid or a base. It typically consists of a weak acid and its conjugate base or a weak base and its conjugate acid. In the case of NaCl (sodium chloride) and HCl (hydrochloric acid), we have a strong acid (HCl) and a neutral salt (NaCl).

When HCl is added to a solution, it dissociates completely into H+ and Cl ions, leading to a decrease in pH. Since NaCl does not provide any weak acid or weak base to counteract the change that the strong acid introduces, the solution lacks the characteristics of a buffer. Thus, it can’t stabilize the pH under stress from additional acidic or basic substances.
