Frequently Asked Questions
What does the dilution formula represent?
C1V1 equals C2V2 states that the total amount of solute stays constant before and after dilution — only the volume of solvent changes, so concentration decreases proportionally as volume increases.
How much water do I need to add?
Subtract the original stock volume (V1) from the calculated final volume (V2) to find how much diluent, typically water or buffer, needs to be added to reach the target concentration.
Does the unit of concentration matter for this calculation?
No, as long as C1 and C2 use the same concentration unit consistently, the formula works regardless of whether you are using molarity, percentage, or any other concentration measure.
