Chapter 9.5, Problem 9.9WE

Interpretation Introduction

Interpretation:

The required volume of $\text{12}\text{.0 M HCl}$ to prepare a $\text{250}\text{.0 mL of 0}\text{.125 M HCl}$ should be calculated.

Concept introduction:

Dilution:

• Dilution is the process, which is used to prepare a low concentrated solution from high concentrated solution.

Volumetric principle:

• In the dilution process, the relationship between initial and final concentrations and volumes of solutions are given in the volumetric equation and it is,

$\begin{array}{l}{\text{M}}_{\text{c}}{\text{×mL}}_{\text{c}}\text{=}{\text{M}}_{\text{d}}{\text{×mL}}_{\text{d}}\\ {\text{M}}_{\text{c}}\text{=}\text{Initial}\text{concentration}\\ {\text{mL}}_{\text{c}}\text{=}\text{Initial}\text{volume}\\ {\text{M}}_{\text{d}}\text{=}\text{Final}\text{concentration}\\ {\text{mL}}_{\text{d}}\text{=}\text{Final}\text{volume}\end{array}$
