I would like to ask about a concentration unit. What does it exactly mean when stock concentration of something is, for example, 5X?
Thank you in advance!
The “X” factor simply indicates that the solution is in a concentrated form that must usually be diluted to a “1X” concentration for use. For example, a 5X concentrated solution must be diluted 5-fold, while a 100X concentrated solution must be diluted 100-fold. The dilutions are usually done using water.
