Chapter 18, Problem 48E

Interpretation Introduction

Interpretation:

The volume of water at $\text{9 ppm}$ required for depleting 50% of ${\text{O}}_{\text{2}}$ in one day is to be calculated.

Concept introduction: The chemical oxygen demand is a method to measure the amount of oxygen that is consumed in a particular reaction. One of the most common applications of chemical oxygen demand is in identifying the amount of pollutants which are oxidized in surface water.

To determine: The volume of water at $\text{9 ppm}$ required for depleting 50% of ${\text{O}}_{\text{2}}$ in one day.
