Understanding the Dilution Factor
The dilution factor is a key concept in chemical engineering, particularly in the analysis of sewage and other solutions. It helps in understanding how concentrated a solution is compared to its original state.
What is the Dilution Factor?
- The dilution factor quantifies how much a sample has been diluted.
- It is crucial for determining the concentration of substances in a diluted solution.
Why Option 'B' is Correct?
- The correct expression for the dilution factor is Volume of diluted sample / Volume of sewage.
- This ratio directly relates the total volume of the final diluted solution to the volume of the original sample (sewage).
Breakdown of the Formula
- Volume of Diluted Sample: This is the total volume after dilution, which includes both the sewage and any added solvent (like water).
- Volume of Sewage: This is the original volume of the sewage that was diluted.
- By dividing the total volume of the diluted sample by the volume of sewage, you obtain the factor by which the sample has been diluted.
Examples of Application
- If you have 100 mL of sewage and dilute it to a total volume of 1 liter (1000 mL), the dilution factor is:
- 1000 mL (diluted sample) / 100 mL (sewage) = 10
- This means the sewage concentration is 10 times less than in its original state.
In conclusion, understanding the dilution factor is essential for accurate chemical analyses, and option 'B' effectively captures the relationship needed for such calculations.
