Verified step by step guidance

Identify the balanced chemical equation for the acid-base reaction. This will help you understand the stoichiometry of the reaction, which is crucial for determining the relationship between the moles of acid and base.

Use the stoichiometry of the balanced equation to determine the number of moles of acid neutralized by the base. This involves using the mole ratio from the balanced equation to convert moles of base to moles of acid.

Calculate the concentration of the acid solution by dividing the number of moles of acid neutralized by the volume of the acid solution used in the titration. This will give you the molarity of the acid solution.

Ensure that the volume of the acid solution is in liters when performing the calculation, as molarity is defined as moles per liter.

Review the calculation steps to confirm that all units are consistent and that the stoichiometry has been correctly applied according to the balanced chemical equation.
