1. What is the Dilution Equation?

The dilution equation calculates the final concentration of a solution after dilution. It's based on the principle of conservation of mass, where the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C_f \) — Final concentration (mol/L)
• \( C_i \) — Initial concentration (mol/L)
• \( V_i \) — Initial volume (L)
• \( V_f \) — Final volume (L)

Explanation: The equation shows that the final concentration is proportional to the ratio of initial to final volumes.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry, biology, medicine, and many industrial processes where precise solution concentrations are required.

4. Using the Calculator

Tips: Enter initial concentration in mol/L, initial and final volumes in liters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my volumes are in milliliters?
A: Convert to liters first (1 L = 1000 mL) or modify the equation to use consistent volume units.

Q2: Does this work for any concentration unit?
A: Yes, as long as you use the same unit for both initial and final concentrations.

Q3: What about serial dilutions?
A: For serial dilutions, apply the equation sequentially for each dilution step.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact, assuming perfect mixing and no chemical reactions.

Q5: Can I use this for solid dilutions?
A: No, this applies only to liquid solutions. For solids, you would need mass-based calculations.
