Dilution concepts
See it
Dilution reduces concentration by adding an appropriate diluent while conserving the amount of solute. The familiar relationship C1V1 = C2V2 is useful when the concentration definitions and units are compatible.
Understand it
C1 and C2 must describe the same substance and compatible concentration units.
V1 is the amount of stock required; V2 is the final diluted volume.
A dilution is useful only if the new measurement becomes practical and the chemistry remains appropriate.
Important boundary
Do not create a dilution merely to make the arithmetic convenient without checking chemical suitability.
Try it
Explain the concept in your own words, then identify what plant, explant, stage, units, source, or observation context would need to be preserved before applying it.
