Advantages:
- Easy to control volume: Using a constant volume simplifies the experiment and eliminates the need for precise volume measurements, reducing potential errors.
- Visual indication of reaction completion: The colour change provides a clear and easy-to-observe indication of when the reaction has completed, making it straightforward to measure the time taken.
Disadvantages:
- Time-consuming: Measuring the time taken for a colour change can be subjective and time-consuming, especially if the colour change is subtle.
- Difficult to accurately determine rate at very low concentrations: At very low concentrations, the colour change might be too slow or faint to be reliably detected within a reasonable timeframe. This can lead to inaccurate rate measurements.
