Frequently Asked Questions

What's the dilution formula?

C1V1 = C2V2, where C is concentration and V is volume, for initial (1) and final (2) states.

What does this formula assume?

That the total amount of solute remains constant - only the solvent volume changes during dilution.

Can I solve for any of the four variables?

Yes, given any three values, you can solve for the fourth.

What units should I use?

Any consistent units work, as long as concentration units match between C1/C2 and volume units match between V1/V2.

Is this useful for lab dilutions?

Yes, this is a standard calculation for preparing diluted solutions from stock solutions in laboratory settings.

Should I always add acid to water, not water to acid?

Yes, for safety when diluting concentrated acids, always add acid to water slowly, never the reverse.

Is my data saved?

No, calculations happen entirely in your browser.

Does this work for serial dilutions?

For a single dilution step, yes - serial dilutions would require applying this formula multiple times in sequence.

Is C1V1=C2V2 the same as molarity dilution?

Yes, this formula is commonly used with molarity as the concentration unit, though it works with other concentration units too.

Is this tool free?

Yes, completely free with no sign-up required.
