Spectrophotometric titrations of acid-base systems using flower extracts containig anthocyanins. Nova [online]. ISSN Considering the attraction of the students' attention by the changes in the colors of vegetable crude extracts caused by the variation of the pH of the medium, the use of these different colors in order what is the importance of acid base titration what is ordinary love principles of spectrophotometric acid-base titrations using the crude extracts as indicators is proposed.

The experimental setup consisted of a simple spectrophotometer, a homemade flow cell and a pump to propel the fluids along the system. Students should be stimulated to choose the best wavelength to monitor the changes in color during the titration. Since the pH of the equivalence point depends on the system titrated, the wavelength must be properly chosen to follow these changes, demonstrating the importance of the correct choice of the indicator.
