A solution of hydrochloric acid (HCl, 25.00 mL) was titrated to completion with 34.55 mL of 0.1020 M sodium hydroxide. What was the concentration of the hydrochloric acid?

Question

Quizplus · Accepted Answer

The concentration of hydrochloric acid can be calculated using the formula $C_1V_1 = C_2V_2$, where $C_1$ and $C_2$ are the concentrations of the acid and base, respectively, and $V_1$ and $V_2$ are the volumes of the acid and base, respectively. Given that $V_1 = 25.00$ mL, $V_2 = 34.55$ mL, and $C_2 = 0.1020$ M, we can solve for $C_1$ as follows: $C_1 = \frac{C_2V_2}{V_1} = \frac{0.1020 \, \text{M} \times 34.55 \, \text{mL}}{25.00 \, \text{mL}} = 0.1410 \, \text{M}$.
