Dilution Factor Calculator
Free Dilution factor Calculator for mixtures & solutions. Enter variables to compute results with formulas and detailed steps.
Formula
DF = C1/C2 | C1V1 = C2V2
The dilution factor is the ratio of initial to final concentration. The dilution equation C1V1 = C2V2 relates initial and final concentrations and volumes, based on conservation of solute moles.
Frequently Asked Questions
What is a dilution factor?
A dilution factor is the ratio of the initial concentration to the final concentration of a solution after dilution. For example, if you dilute a 10 M solution to 1 M, the dilution factor is 10 (or 1:10). It tells you how many times the original solution has been diluted. The dilution factor can also be expressed as the ratio of final volume to initial volume of the stock solution used. In serial dilutions, the overall dilution factor is the product of individual dilution factors at each step.
What is a serial dilution and when should I use one?
A serial dilution is a series of stepwise dilutions where each step uses the previously diluted solution as the stock for the next dilution. This technique is essential when you need very large dilution factors that would be impractical in a single step. For example, a 1:1,000,000 dilution is more accurately achieved by six sequential 1:10 dilutions. Serial dilutions are standard practice in microbiology for colony counting, in immunology for antibody titers, and in analytical chemistry for creating calibration curves spanning several orders of magnitude.
How does the dilution formula work?
The dilution formula is C1V1 = C2V2, where C is concentration and V is volume. If you have 100 mL of 2M HCl and need 0.5M, solve: 2 x 100 = 0.5 x V2, so V2 = 400 mL total volume. Add 300 mL of water to 100 mL of stock solution. Always add acid to water, never the reverse.
