Solution Dilution 22.10.2013
In general, it is not practical to store solutions of every possible concentration. Instead, we generally store fairly concentrated solutions, so-called stock solutions.
Dilute solutions, then, can be prepared from stock solutions. A concentrated solution has a relatively large amount of dissolved solute.
A dilute solution has a small amount.
When a solution diluted, the amount of solute remains constant between the initial (i) and final (f) solution prepared.
