dilution series

A dilution series is a stepwise method used to decrease the concentration of a substance, typically a solution, to a desired level. It involves taking a small amount of the original solution and mixing it with a known volume of a diluent (like water) in successive steps. For example, you might take 1 milliliter of a solution, add it to 9 milliliters of water, creating a tenfold dilution. This process is repeated multiple times to achieve increasingly lower concentrations. Dilution series are commonly used in laboratories for experiments, testing, and determining reactions at various concentrations.
