Titration ColorCam

Sound and Touch Feedback for Detecting Titration Endpoints

The idea of Titration ColorCam was conceived in an effort to develop a smartphone aid that would enable colorblind and visually impaired students to perform acid-base titration experiments in chemistry labs. The app analyzes the color changes involved in a titration, translates data into sound (beeps) and tactile (vibrations) feedback for detecting an endpoint.

The application currently supports the following indicators:

1. Crystal Violet

2. Cresol Red

3. Thymol Blue

4. 2, 4-Dinitrophenol

5. Bromophenol Blue

6. Methyl Orange

7. Bromocresol Green

8. Methyl Red

9. Eriochrome Black T

10. Bromocresol Purple

11. Bromothymol Blue

12. Phenol Red

13. M-Nitrophenol

14. Phenolphthalein

15. Thymolphthalein

16. Starch

The application is currently in beta state. Please report any bugs and suggestions to [email protected], we will be happy to improve the app based on your feedback.
