Suggest one reason for the anomalous result in Table 1.

The anomalous result of 28.1 cm³ is significantly higher than the other concordant results (around 24.4 cm³). This indicates that too much acid was added from the burette. A likely reason is that the student added the acid too quickly near the endpoint and "overshot" it, meaning they went past the point where the indicator changed colour permanently. Other possible reasons include misreading the final volume on the burette or not swirling the flask properly, leading to a localised colour change that was missed.
