WebThe pH values of basic solutions are always above 7. Bases react with acids to form salts. Such a chemical reaction is called an acid-base neutralisation reaction. It can be noted that the pH of an aqueous solution of the salt formed from an acid-base neutralisation reaction is dependent on the strength of the parent acid and the parent base. WebMar 20, 2024 · A solution of a weak acid is also a buffer solution. When a weak acid reacts with a weak base an equilibrium mixture is produced. An acid base reaction is the removal of hydrogen ions from the acid and its addition to the base. The reception of proton by a base produces its conjugate acid, which is the base with a hydrogen ion added.
