* Salt of a strong acid and a strong base: Magnesium chloride is formed from the reaction of magnesium hydroxide (Mg(OH)₂, a strong base) and hydrochloric acid (HCl, a strong acid).

* Hydrolysis: When salts dissolve in water, they can undergo hydrolysis, where the ions react with water to produce H⁺ or OH⁻ ions. However, in the case of MgCl₂, neither Mg²⁺ nor Cl⁻ ions have a significant tendency to hydrolyze.

* Neutral pH: Since neither ion significantly affects the pH of the solution, the overall solution remains neutral.

In summary, magnesium chloride is a neutral salt because it is formed from a strong acid and a strong base, and its ions do not significantly hydrolyze in water.
