1. What is the Dilution Formula?

The dilution formula \( C_f = C_i \times \frac{V_i}{V_f} \) calculates the final concentration of a solution after dilution, where \( C_i \) is the initial concentration, \( V_i \) is the initial volume, and \( V_f \) is the final volume after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_f \) — Final concentration (various units)
• \( C_i \) — Initial concentration (various units)
• \( V_i \) — Initial volume (L)
• \( V_f \) — Final volume (L)

Explanation: This formula demonstrates the inverse relationship between concentration and volume - as volume increases through dilution, concentration decreases proportionally.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory settings, pharmaceutical preparations, chemical manufacturing, and various scientific experiments where precise concentrations are required.

4. Using the Calculator

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.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for concentration?
A: The calculator accepts any concentration units (mg/mL, M, %, etc.) as long as you're consistent. The result will be in the same units as your initial concentration.

Q2: Can I use different volume units?
A: While the calculator uses liters, you can use any volume unit as long as both \( V_i \) and \( V_f \) use the same unit (mL, L, etc.).

Q3: What if my final volume is less than initial volume?
A: This would represent concentration rather than dilution, but the formula still applies mathematically. However, physically this typically requires evaporation or removal of solvent.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your measurements and the assumption that the dilution is homogeneous.

Q5: Can this be used for serial dilutions?
A: For serial dilutions, you would need to apply this formula sequentially for each dilution step in the series.
