Dilution Formula:
| From: | To: |
The chemical dilution percentage formula calculates the final concentration of a solution after dilution. It is based on the principle that the amount of solute remains constant during the dilution process, while the total volume increases.
The calculator uses the dilution formula:
Where:
Explanation: The formula calculates the new concentration after diluting an initial solution by adding more solvent. The final concentration is proportional to the ratio of initial to final volumes.
Details: Accurate dilution calculations are essential in chemistry, pharmaceuticals, laboratory work, and industrial processes to achieve desired concentrations for experiments, manufacturing, and quality control.
Tips: Enter the initial percentage concentration, initial volume, and final volume after dilution. All values must be positive numbers. The calculator will compute the final percentage concentration.
Q1: Can this formula be used for any concentration unit?
A: Yes, the formula works for any consistent concentration units (%, mg/L, M, etc.) as long as the same unit is used for both initial and final concentrations.
Q2: What if I need to dilute to a specific final concentration?
A: Rearrange the formula to solve for the required final volume: \( V_f = \%i \times V_i / \%f \)
Q3: Does this formula account for density changes?
A: For most practical purposes with dilute solutions, density changes are negligible. For concentrated solutions, additional corrections may be needed.
Q4: Can I use different volume units?
A: Yes, as long as both volume measurements use the same units (mL, L, etc.), the calculation remains valid.
Q5: What is the maximum accuracy of this calculation?
A: The accuracy depends on the precision of your measurements. The formula itself is mathematically exact for ideal solutions.
