Chapter 9, Problem 9.70QP

Interpretation Introduction

Interpretation:

The final concentration of the ${\text{KNO}}_{\text{3}}$ solution should be determined.

Concept introduction:

Volumetric principle:

• In the neutralization process, the volume and concentration of initial components are equal to the volume and concentration of the final components.
• In the dilution of the chemical solutions are using this 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,

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