Abstract：The water,30%methanol solution and 60%methanol solution were titrated respectively by KOH solu?tion and HCl solution, and the pH values of the solution were determined by using the potentiometric method. It is found that the methanol has a certain effect on the pH value of the solution due to the difference of the permit?tivity and the proton self delivery constant, and the effect is that when the methanol concentration is great, the im?pact is great, and when the acidity of the solution reaches a certain value, the impact will be stable in a certain value, and the effect is stable.
