Abstract:
Objective: To improve the standardization method for ethanol potassium hydroxide volumetric solution. Methods: A new potentiometric titration method was established and compared with the indicator method described in Chinese Pharmacopeia (2010 edition) . Results:There was no significant difference between the results of the potentiometric method and the indicator method( P>0. 05). Furthermore, the potentiometric titration had significant jump range, good precision and high reliability. Conclusion:The po-tentiometric method can be used in the standardization of ethanol potassium hydroxide volumetric solution.
