The reaction between acids and bases in water to make the solution shows the treasure as acid base or middle, which consider as 2 cases.
1. Acid and base, already have reacted acid or base left. If the remaining acid solution showed property as acid If the base remaining solution show property as base.
2. The reaction acid and base with all, salt and water. The solution of salt from the reaction will show the property as acid base or middle, depending on the type of salt that comes from the acid and base of any type. Because each type of salt will split and the reaction with water is called hydrolysis. Make the solution acid and base properties display differently.
