Chapter 8, Problem 8.85AP

a.

Summary Introduction

To determine:

The final concentration of $2.0\text{L}$ of a $3.0\text{M}$ ${\text{HNO}}_3$ solution that has been diluted to a final volume of $6.0\text{L}$.

Introduction:

Dilution is the process of lowering the concentration of a solution by the addition of more solvent. In this process the amount of solute does not change but there occurs a change in volume; therefore, the concentration of the solution decreases. It is mathematically expressed as,

$C_1{V}_1=C_2{V}_2$ (1)

Where,

• $C_1$ is the initial concentration of the solution.
• $V_1$ is the initial volume of the solution.
• $C_2$ is the final concentration of the solution.
• $V_2$ is the final volume of the solution

Summary Introduction

To determine:

The final concentration of $0.50\text{L}$ of a $6.0\text{M}$ $\text{KOH}$ solution that has been diluted to a final volume of $4.0\text{L}$.

Introduction:

Dilution is the process of lowering the concentration of a solution by the addition of more solvent. In this process the amount of solute does not change but there occurs a change in volume; therefore, the concentration of the solution decreases. It is mathematically expressed as,

• $V_1$ is the initial volume of the solution.
