Describe a scenario where a seemingly minor oversight could lead to a gross error in a titration analysis.

Imagine an analyst titrating a sample with a standardized solution. If they accidentally add a significant amount of the titrant *before* starting the titration process, without realizing it, this constitutes a gross error. The initial volume is incorrect, and the subsequent readings will be skewed, leading to a completely inaccurate result. This seemingly minor oversight – forgetting to account for the pre-titration volume – can have a major impact.
