Chapter 4, Problem 47E

Interpretation Introduction

Interpretation:

The size of pipet and volumetric flask that can be used to prepare a 0.0125 M ${\text{K}}_{\text{2}}{\text{CrO}}_{\text{4}}$ solution from a 0.250 M ${\text{K}}_{\text{2}}{\text{CrO}}_{\text{4}}$ solution needs to be determined.

Concept introduction:

From a given solution, the solution with less molarity can be prepared by dilution.

According to dilution law,

$M_1{V}_1=M_2{V}_2$

Here, $M_1$ is initial molarity, $M_2$ is final molarity, $V_1$ is initial volume and $V_2$ is final volume.
