Here are the essential concepts you must grasp in order to answer the question correctly.
Neutralization Reaction
A neutralization reaction occurs when an acid reacts with a base to produce water and a salt. In this case, hydrochloric acid (HCl) reacts with barium hydroxide (Ba(OH)2). The balanced chemical equation helps determine the stoichiometric relationships between the reactants, which is essential for calculating the volumes needed for complete neutralization.

Molarity (M)
Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. It is expressed in moles per liter (mol/L). In this question, the molarity of HCl and Ba(OH)2 solutions is crucial for determining how much of each solution is required for the reaction, as it allows for the conversion between volume and the amount of substance.

Stoichiometry
Stoichiometry involves the calculation of reactants and products in chemical reactions based on the balanced equation. It allows us to determine the proportions of substances consumed and produced. In this scenario, stoichiometry is used to relate the moles of HCl needed to neutralize the moles of Ba(OH)2 present in the solution, facilitating the calculation of the required volume of HCl.
