Definition of dilution and dilution factor?

Dilution is the process of reducing the concentration of a substance by adding more solvent. The dilution factor is the ratio of the final volume of the diluted solution to the initial volume of the concentrated solution. It is used to calculate the new concentration after dilution.


How do you make a 1 to 5 dilution?

To make a 1 to 5 dilution you mix 1 part of your substance with 4 parts water. ie: Mix 1 tablespoon of creamer with 4 tables spoons of coffee, and the coffee is 1/5 creamer now.

How would you prepare 20 ml of a 1 to 400 dilution?

To prepare 20 ml of a 1:400 dilution, you would mix 20 ml of the original solution with 7980 ml (20 ml x 400) of the diluent (such as water or buffer). This will give you a final solution with a concentration that is 1/400th of the original solution.

How do you prepare 1 is to 100 dilution in small volume?

To prepare a 1:100 dilution in a small volume, mix 1 part solute with 99 parts solvent (such as 1 ml solute with 99 ml solvent). For example, to dilute 1 ml of a substance in 99 ml of water, mix thoroughly to ensure a homogeneous solution. Note that maintaining accurate measurements and thorough mixing are crucial for successful dilution.


How do you do parallel dilution?

To perform parallel dilution, prepare a series of tubes with known volumes of the solution to be diluted. Then add a known volume of diluent to each tube to achieve the desired dilution factor. Mix each tube thoroughly and label them to keep track of the dilution factor.
