摘要
Abstract
Absorption spectrum of violet cabbage pigment and the difference in different pH test was studied. The results show that the maximum absorption wavelength (γmax) moves to longer wavelengths as the pH increasing. There are four tautomers of violet cabbage pigment, showing different color under different pH. The violet cabbagepigment is a good acid-alkali indicator, and can be applied in daily use.
