1. What is the Dilution Equation?

The dilution equation \( C_2 = C_1 \times \frac{V_1}{V_2} \) describes how to calculate the final concentration of a solution after dilution. This is fundamental in laboratory work when preparing solutions of desired concentrations from stock solutions.

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 proportional to the ratio of initial to final volumes.

3. Importance of Accurate Dilution

Details: Precise dilutions are critical in laboratory experiments, pharmaceutical preparations, and analytical chemistry to ensure accurate results and proper chemical reactions.

4. Using the Calculator

Tips: Enter all values in consistent units (mol/L for concentration, liters for volume). Ensure all values are positive numbers. The calculator will compute the final concentration after dilution.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units?
A: The calculator uses mol/L and liters for consistency. Convert your units before entering values or adjust the result accordingly.

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution. The equation still applies but you're effectively making a more concentrated solution.

Q3: How precise should my measurements be?
A: Precision depends on your application. Analytical work typically requires 4+ significant figures, while general lab work may need 2-3.

Q4: Does this work for serial dilutions?
A: For serial dilutions, you need to apply the equation sequentially for each dilution step.

Q5: What about non-aqueous solutions?
A: The equation works for any solvent as long as the solute doesn't react with or change properties in the solvent.
