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.
