Solution Dilution Calculator
Solution Dilution Calculator
Enter any three parameters out of four (C₁, V₁, C₂, V₂) - the calculator will find the fourth.
Dilution Formula:
C₁V₁ = C₂V₂
- C₁ = Initial concentration
- V₁ = Initial volume
- C₂ = Final concentration
- V₂ = Final volume
How dilution works:
When you dilute a solution, you add solvent (usually water) to decrease the concentration. The amount of solute remains constant, but it's distributed in a larger volume.
Units to use:
- Concentration: mol/L (molarity)
- Volume: L (liters)
- Make sure all units are consistent for accurate results
Applications:
- Laboratory solution preparation
- Chemistry homework problems
- Pharmaceutical calculations
- Biological sample preparation
- Quality control in manufacturing
Example:
If you have 0.5 L of 2 M solution and want 1 M final concentration, the calculator shows you need a final volume of 1 L (add 0.5 L of water).
Frequently Asked Questions
What is the dilution formula?
C₁V₁ = C₂V₂ - this basic formula for dilution calculations means the amount of substance before and after dilution remains unchanged.
How to properly use this calculator?
Enter three of the four values: initial concentration (C₁), initial volume (V₁), final concentration (C₂), or final volume (V₂). The calculator will compute the fourth value.
What units should I use?
Enter concentration in mol/L and volume in liters. All values must be in consistent units for correct results.
What problems is this calculator suitable for?
Useful for students, laboratory technicians, and teachers when solving chemistry, biology, medicine, pharmacy problems, etc.
What if I enter wrong units?
Wrong units can lead to incorrect results. For example, if volume is in mL instead of L, the result will be 1000 times larger or smaller.
Can this calculator be used for alcohol or medicine dilution?
Yes, the formula applies to any solutions where the amount of active substance doesn't change - including ethanol, iodine, medications, etc.
