Three acid samples are prepared for titration by $0.01 M$ $\mathrm{NaOH}:$ 1. Sample 1 is prepared by dissolving $0.01 \mathrm{~mol}$ of $\mathrm{HCl}$ in $50 \mathrm{~mL}$ of water. 2. Sample 2 is prepared by dissolving $0.01 \mathrm{~mol}$ of $\mathrm{HCl}$ in $60 \mathrm{~mL}$ of water. 3. Sample 3 is prepared by dissolving $0.01 \mathrm{~mol}$ of $\mathrm{HCl}$ in $70 \mathrm{~mL}$ of water. (a) Without performing a formal calculation, compare the concentrations of the three acid samples (rank them from highest to lowest). (b) When the titration is performed, which sample, if any, will require the largest volume of the $0.01 M \mathrm{NaOH}$ for neutralization?

Key Concepts

Titration Equivalence

Titration equivalence is reached when the moles of titrant added are stoichiometrically equal to the moles of the analyte in the solution. This concept is key in determining the volume of titrant required to completely neutralize an acid or base during a titration.

Stoichiometry of Acid-Base Reactions

Stoichiometry in acid-base reactions involves the quantitative relationship between the acid and base reacting in a neutralization process. It determines how many moles of titrant are needed to react completely with a known amount of analyte based on balanced chemical equations.

Dilution Principle

The dilution principle explains that when a fixed amount of solute is dissolved in varying volumes of solvent, the resulting concentration changes inversely with the volume. A larger volume results in a lower concentration, even though the number of moles of the solute remains constant.

Molarity

Molarity refers to the number of moles of a solute divided by the volume of the solution in liters. In acid-base contexts, it determines the concentration, which influences how many moles of acid or base are present in a given volume of solution.
