Sodium chloride (\(\text{NaCl}\)) is a salt formed from the neutralization reaction of a strong acid (hydrochloric acid, \(\text{HCl}\)) and a strong base (sodium hydroxide, \(\text{NaOH}\)). When it dissolves in water, neither the sodium ions nor the chloride ions undergo significant hydrolysis (reaction with water). As a result, the concentrations of \(\text{H}^{+}\) and \(\text{OH}^{-}\) ions in the water remain essentially unchanged, and the solution maintains a neutral pH of approximately 7.
