Question

How do you calculate dilution factor?

Answer 1

By using dilution factor we can find the amount of original stock solution present in the given total solution after doing dilution. Dilution factor is going to be used in a vast manner in volumetric analysis to find the concentration of the chemicals.

Complete answer:
- In the question it is given how to calculate the dilution factor.
- There is a formula to calculate the dilution factor of a chemical solution and it is as follows.
Dilution factor $=\frac{{{V}_{i}}}{{{V}_{f}}}$
- Here ${{V}_{f}}$ is called as the final volume and ${{V}_{i}}$ is called as the initial volume of the solutions.
- Dilution factor is the ratio of volume at initial concentration to the volume at final concentration means after dilution.
- The initial volume is always called a stock solution and the final volume is called a diluted solution.
- In volumetric analysis to find the concentration of the chemical present in the stock solution we have to do the dilution by using dilution factor.
- Dilution factor does not explain what the volume of the solution is and what is the final volume of the solution, just it tells the ratio of initial volume to final volume.

Note:
Dilution means reducing the concentration of the original solution by adding a known or unknown amount of water to the original or stock solution. We can calculate the final volume of the solution if we the initial volume and dilution factor value by using the below formula.
${{V}_{f}}=Dilution\text{ }factor\times {{V}_{i}}$
