1. What is the Dilution Equation?

The dilution equation (C2 = C1 × (V1 / V2)) calculates the final concentration of a solution after dilution. It's fundamental in chemistry for 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 Dilution Calculations

Details: Accurate dilution calculations are essential for preparing solutions in laboratories, industrial processes, and educational settings. They ensure proper concentrations for chemical reactions and analyses.

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: Can this equation be used for any solution?
A: Yes, the equation works for any solution as long as the solute doesn't react with the solvent during dilution.

Q2: What if I need to prepare a specific volume?
A: Calculate the required initial volume (V1) by rearranging the equation: V1 = (C2 × V2) / C1.

Q3: Does temperature affect dilution calculations?
A: Temperature affects solution volume slightly, but for most practical purposes at constant temperature, the equation holds.

Q4: How precise should my measurements be?
A: Precision depends on your application. Analytical work requires more precise measurements than general lab work.

Q5: Can I use different volume units?
A: Yes, as long as V1 and V2 use the same units (mL, L, etc.), the calculation remains valid.
