Titration ColorDarts

“Is this solution pink enough?”: a persisting question when it comes to phenolphthalein-based titration experiment, one that novice scientists often ask their lab instructors. Lab instructors usually answer the inquiry with remarks such as “Looks like you have overshot the endpoint” or “Perhaps, you should check the amount of the indicator and redo.”

Titration ColorDarts (TCD) is aimed to enable the learners to identify the probable errors in their titration experiment independently. TCD provides a real-time feedback report which includes gamified performance scores, question prompts and hints for taking measures to resolve the errors in the subsequent experiment iterations by self-assessment.

The app has been designed and developed at the Light Lab, Department of Chemical Sciences, Indian Institute of Science Education and Research (IISER) Kolkata.

Team:
Balraj Rathod (Project Research Assistant)
Prof. Subhajit Bandyopadhyay (Group PI, Light Lab-IISER Kolkata)

This project was done in an academic collaboration with Prof Sahana Murthy, Educational Technology, Indian Institute of Technology Bombay

The app is still in a beta stage. Please report any bugs or suggestions at bandyopadhyaylab@gmail.com.
