Conclusion
The study presents a reliable and efficient method for performing potentiometric and spectrophotometric titrations using a computer-controlled system.
Supporting Evidence
- Replicate potentiometric titrations of glycines showed a relative standard deviation in titre of 1.035%.
- Replicate spectrophotometric titrations of bromophenol blue yielded a pKa of 3.898 ± 0.075.
- The system allows for machine-readable data, enhancing data manipulation and analysis.
Takeaway
This study shows how a computer can help scientists measure things more accurately and quickly when mixing liquids.
Methodology
The study describes the construction and operation of a computer-controlled titrator that integrates potentiometric and spectrophotometric techniques.
