Benzoic acid, $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH}$, is sometimes used as a primary standard for the standardization of solutions of bases. A $1.862-\mathrm{g}$ sample of this acid is neutralized by $35.00 \mathrm{~mL}$ of $\mathrm{NaOH}$ snlution. What is the molarity of the hase solution? $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH}(\mathrm{s})+\mathrm{NaOH}(\mathrm{aq}) \longrightarrow$

Key Concepts

Acid-Base Titration

Acid-base titration is an analytical technique used to determine the concentration of an acid or base in a solution by neutralizing it with a titrant of known concentration. The point where the reactants completely neutralize each other, often indicated by a specific indicator or pH measurement, allows for the precise calculation of the analyte's concentration.

Molarity Calculation

Molarity is defined as the number of moles of a solute per liter of solution. Calculating molarity involves converting the mass of a solute to moles using its molar mass and then dividing by the volume of the solution in liters, enabling the quantification of concentration in volumetric analysis.

Primary Standard

A primary standard is a pure, stable compound with known composition and high purity that is used to accurately determine the concentration of other solutions through titration. Its properties allow it to be weighed precisely, ensuring that the number of moles calculated from its mass is exact.

Stoichiometry and Balanced Reactions

Stoichiometry involves using the balanced chemical equation to determine the quantitative relationships between reactants and products in a chemical reaction. In titrations, the stoichiometric relationship between the acid and base allows one to calculate the number of moles involved, which is crucial for determining unknown concentrations.
