1. What is the C1V1 = C2V2 Equation?

The C1V1 = C2V2 equation, also known as the dilution equation, is used to calculate the concentration of a solution after dilution or to determine the volume needed to achieve a desired concentration.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

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

Explanation: The equation shows that the product of initial concentration and volume equals the product of final concentration and volume after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry, biology, and medicine for preparing solutions of precise concentrations for experiments, medications, and laboratory procedures.

4. Using the Calculator

Tips: Enter all values in consistent units (mol/L for concentrations, liters for volumes). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units?
A: Yes, but all volumes must be in the same units and all concentrations must be in the same units.

Q2: What if I know C2 and need to find V1?
A: The equation can be rearranged: \( V_1 = \frac{C_2 \times V_2}{C_1} \)

Q3: Does this work for any dilution?
A: Yes, as long as the solute amount remains constant (no additional solute is added during dilution).

Q4: What's the difference between dilution and concentration?
A: Dilution is adding solvent to decrease concentration, while concentration is removing solvent to increase concentration.

Q5: How precise should my measurements be?
A: The precision depends on your application. For most laboratory work, 3-4 significant figures are appropriate.
