Solution

Dilution:

  • Dilution is known as the process of decreasing the concentration of a solute in a solution, simply by mixing it with more solvent like adding more water to the solution.
  • To dilute a solution basically means to add more solvent without the addition of more solute.

Dilution factor:

  • Dilution Factor is the formula used for making a dilute solution without calculating concentrations from the concentration term formulas.
  • The formula for dilution Factor is given by:

DilutionFactor=FinalVolumeinitialVolume

Example:

  • Making 500mL of a 1:250 dilution:
  • Formula used as =FinalVolumeinitialVolume=DF
  • By putting the values: = (500mL)inititalVolume=250(DilutionFactor)
  • Hence, the Solute Volume =500mL250=2.00mL

Therefore, the dilution factor can be calculated by using the above-mentioned formula as: DilutionFactor=FinalVolumeinitialVolume.
