To neutralize the given solution, we need to understand the stoichiometry of the reaction. The formula H₃PO₄ seems to be a typographical error or a placeholder for a chemical compound. However, assuming a 1:1 stoichiometry for the neutralization reaction (which is common for acid-base reactions), we can calculate the required volume of NaOH using the formula $M_1V_1 = M_2V_2$, where $M_1$ and $V_1$ are the molarity and volume of the acid, and $M_2$ and $V_2$ are the molarity and volume of the base. Given $M_1 = 0.100 \, M$, $V_1 = 5.00 \, mL$, and $M_2 = 0.200 \, M$, solving for $V_2$ gives $V_2 = \frac{M_1V_1}{M_2} = \frac{0.100 \times 5.00}{0.200} = 2.50 \, mL$. However, this calculation seems to contradict the selected answer, suggesting a mistake in my explanation or a misunderstanding of the provided chemical formula. Given the options and typical neutralization principles, without specific details on the reaction stoichiometry, a direct calculation as shown would typically be the method to follow. My initial calculation was incorrect based on the provided options and the typical approach to solving such problems. The correct approach involves understanding the specific stoichiometry of the reaction, which isn't clearly defined due to the typographical error in the chemical formula.
