The paper presents two potentiometric methods that can be effectively used to study the acid-alkaline properties of the surface of powders: the direct potentiometric method and the method of potentiometric titration of aqueous suspensions. It was established that the results obtained using these methods complement each other and allow to obtain the most complete characteristics of the acid-alkaline properties of the surface of powder materials.
