Chapter 13, Problem 92E

Interpretation Introduction

Interpretation:

The volume of potassium sulfide $\left({\text{K}}_2\text{S}\right)$ solution required to completely react with $\text{Co(NO3)2}$ is to be determined

Concept Introduction:

Molarity can be defined as the number of moles of solute per liter of solution. The molarity of the dilute solution can be expressed as follows:

$M_1{V}_1=M_2{V}_2$…… (1)

Here, $M_1$ and $V_1$ are the molarity and volume of the initial concentrated solution and $M_2$ and $V_2$ are the molarity and volume of the final diluted solution.
