1. What is the Dilution Equation?

The dilution equation \( C_2 = C_1 \times \frac{V_1}{V_2} \) 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 concentration decreases proportionally as volume increases, maintaining the same amount of solute in a larger volume.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry, biology, and medicine for preparing solutions of precise concentrations from stock solutions.

4. Using the Calculator

Tips: Enter all values in consistent units (mol/L for concentration, liters for volume). Ensure all values are positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution, and isn't what this calculator is designed for.

Q3: How precise should my measurements be?
A: Precision depends on your application. For most lab work, 4 significant figures is sufficient.

Q4: Does this work for any solute?
A: Yes, as long as the solute is completely dissolved and doesn't react with the solvent.

Q5: Can I use this for serial dilutions?
A: For serial dilutions, you would need to perform this calculation for each dilution step.
