Serial dilution problem You have a stock of 5% SDS. You take some of that stock and dilute it 4-fold in tube #1. the tubes hold 1.5ml. give an example of how much 5% stock and how much water you would use to make 4 fold dilution - volume of 5% stock ? - volume of water? - How much volume transferred? - if you took a sample out of tube 2 and did another 4 fold dilution, what concentration...

Dilution is a process in which the concentration of a solution is lowered by adding more...
Dilution is a process in which the concentration of a solution is lowered by adding more solvent. Some of the reasons dilutions are performed are to minimize measurement errors when preparing a series of solutions at different concentrations, to save time and laboratory space, and to make more accurate measurements on an analytical balance when the target concentration is very low. The new concentration of a diluted solution can be determined from the following equation, sometimes called the dilution equation,...
