General Dilution Formula:
| From: | To: |
The dilution formula \( C_f = C_i \times \frac{V_i}{V_f} \) is used to calculate the final concentration of a solution after dilution, where the initial concentration is known and volumes are measured.
The calculator uses the dilution formula:
Where:
Explanation: The formula demonstrates that the final concentration is proportional to the ratio of initial to final volumes, maintaining the conservation of mass principle.
Details: Accurate dilution calculations are essential in chemistry, biology, medicine, and various industrial processes where precise concentration adjustments are required for experiments, medications, and manufacturing.
Tips: Enter initial concentration in appropriate units, initial volume in liters, and final volume in liters. All values must be positive numbers greater than zero.
Q1: What units should I use for concentration?
A: The calculator accepts any concentration units as long as they are consistent. Common units include mol/L, g/L, mg/mL, or percentage concentrations.
Q2: Can I use different volume units?
A: While the calculator uses liters, you can use any volume unit as long as both Vi and Vf are in the same units (mL, L, etc.).
Q3: What if I need to calculate initial concentration instead?
A: The formula can be rearranged: \( C_i = C_f \times \frac{V_f}{V_i} \) to solve for initial concentration.
Q4: Does this formula work for serial dilutions?
A: For serial dilutions, you would apply the formula sequentially for each dilution step in the series.
Q5: Are there limitations to this formula?
A: This formula assumes ideal mixing conditions and that the solute doesn't significantly affect the solution volume. For very concentrated solutions, additional corrections may be needed.
