A student standardizes a sample of an \(\text{Fe}^{2+}\text{(aq)}\) solution by titrating a \(25.00\text{ mL}\) aliquot with standardized \(0.0200\text{ M }\text{KMnO}_4\text{(aq)}\) in an acidic medium according to the balanced equation below:

\[ 5\,\text{Fe}^{2+}\text{(aq)} + \text{MnO}_4^-\text{(aq)} + 8\,\text{H}^+\text{(aq)} \rightarrow 5\,\text{Fe}^{3+}\text{(aq)} + \text{Mn}^{2+}\text{(aq)} + 4\,\text{H}_2\text{O(l)} \]

Before beginning the titration, an air bubble was trapped in the buret tip below the stopcock. During the titration, the air bubble was dislodged and filled with titrant solution as liquid was delivered into the flask to reach the light-pink endpoint. Which of the following correctly predicts the effect of this error on the calculated \([\text{Fe}^{2+}]\) and identifies the proper procedural modification to eliminate this source of error?
