Hypothesis
The study aims to investigate the pH changes during the formaldehyde-sulphite clock reaction using a computerized pH measuring system.
Conclusion
The study successfully monitored pH changes in the formaldehyde-sulphite clock reaction and demonstrated the effects of aerial oxidation on the reaction.
Supporting Evidence
- The study utilized a computerized pH measuring system to monitor pH changes.
- Data acquisition and treatment were achieved through the use of ASYST software.
- The results indicated that aerial oxidation of sulphite significantly affected the reaction.
Takeaway
This study used a computer to measure how the pH changes when formaldehyde and sulphite mix, showing that the reaction can change quickly.
Methodology
A computerized pH monitoring system was used to measure pH changes in real-time during the reaction.
Limitations
The study's results may be affected by the accuracy of the chemicals used and the conditions under which the experiments were conducted.
