摘要：
The dispersion of nanosilica that was modified and original in organic solvents could be judged directly by using methyl red as the indicator, and the principle of color development was also discussed. A method has been developed for the determination of the acidity of solid surfaces, which consists of titration of the solid suspended in benzene with n-butyl amine, using neutral red as the indicator. Basic indicator forms a red color on acidic solids, and the end-point of the titration is the disappearance of the red color.
