1. What is the C1V1 = C2V2 Equation?

The C1V1 = C2V2 equation describes the principle of dilution where the product of initial concentration and volume equals the product of final concentration and volume. It's used to calculate how to dilute a solution to achieve a desired concentration.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

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

Explanation: The equation maintains the conservation of mass principle, where the amount of solute remains constant before and after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are crucial in chemistry, biology, medicine, and many industrial processes where precise concentrations are required.

4. Using the Calculator

Tips: Enter all values in consistent units (percentage for concentration, liters for volume). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units for volume?
A: Yes, as long as V1 and V2 use the same units (mL, L, etc.), the calculation will be correct.

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 concentration units?
A: Yes, as long as C1 and C2 use the same units (%, M, mg/mL, etc.).

Q4: What's the maximum dilution possible?
A: Theoretically unlimited, but practically limited by the solubility and detection limits of the solute.

Q5: Does temperature affect the calculation?
A: The calculation assumes volume remains constant. For precise work with temperature-sensitive solutions, temperature compensation may be needed.
