Dilution
Calculator
A free dilution Factor Calculator could be an important tool for chemistry and biology students in the lab. The DF is a very important concept in chemistry and biology where it is used to describe how much a sample has been diluted. It is commonly expressed as a ratio that indicates the number of parts of solvent to one part of solute. This concept is often used for accurate experiments, calculations, and data analysis. As such, understanding and calculating the DF is essential for accurately preparing solutions with desired concentrations. It ensures that experiments, reactions, or analyses are performed under controlled and repeatable conditions.
The Dilution Factor Calculator Formula
The dilution factor (DF) is calculated using the following formula:
DF=Final Volume (Vf)/Initial Volume (Vi)=Final Concentration/Initial concentration.
Note
- DF > 1: The solution has been diluted. For example, if DF = 10, it means the original solution has been diluted tenfold.
- DF = 1: No dilution has occurred; the final volume is the same as the initial volume.
- DF < 1: This is uncommon in standard practice because it would imply a concentration increase rather than a dilution.
Example 1: You have a 1 M (molar) solution and you dilute it to a final volume of 1 liter from an initial 100 ml. The final concentration is 0.1 M. Applying the formula:
DF = C1 / C2 = 1 M / 0.1 M = 10
or
DF = V2 / V1 = 1000 ml / 100 ml = 10
Thus, the dilution factor is 10.
Example 2: If you need to dilute a solution from 0.5 M to 0.05 M, and you start with 200 ml. V2 is what you need to find.
DF = C1 / C2 = 0.5 M / 0.05 M = 10
V2 = DF * V1 = 10 * 200 ml = 2000 ml
Thus, you need to dilute the solution to a total volume of 2000 ml.
