1. What is the Dilution Equation?

The dilution equation (C2 = C1 × (V1/V2)) 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:

• \( C_1 \) — Initial concentration (mol/L)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume after dilution (L)
• \( C_2 \) — Final concentration (mol/L)

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

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 all values in consistent units (mol/L for concentration, liters for volume). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different volume units?
A: Yes, as long as both V1 and V2 are in the same units (e.g., both in mL or both in L).

Q2: What if my final volume is less than initial volume?
A: The equation still works mathematically, but physically this would represent concentration, not dilution.

Q3: Does this work for any solute?
A: Yes, as long as the solute doesn't react with the solvent or change its properties during dilution.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact, but real-world accuracy depends on measurement precision.

Q5: Can I use this for serial dilutions?
A: Yes, but you would need to apply the equation sequentially for each dilution step.
