1. What is the Dilution Formula?

The dilution formula calculates the final concentration of a solution after dilution. It's based on the principle that the amount of solute remains constant before and after dilution, expressed as \( C_1 \times V_1 = C_2 \times V_2 \).

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_1 \) — Initial concentration (any unit)
• \( V_1 \) — Initial volume (mL or L)
• \( V_2 \) — Final volume after dilution (mL or L)
• \( C_2 \) — Final concentration (same unit as C1)

Explanation: The formula maintains mass balance - the total amount of solute remains constant during the dilution process.

3. Importance of Dilution Calculation

Details: Accurate dilution calculations are essential in laboratory work, pharmaceutical preparations, chemical manufacturing, and various scientific experiments where precise concentrations are required.

4. Using the Calculator

Tips: Enter initial concentration in any unit, initial volume and final volume in consistent units (either both mL or both L). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units for volume?
A: Yes, but V1 and V2 must use the same units (both mL or both L) for the calculation to be accurate.

Q2: What if I need to calculate V1 or V2 instead?
A: The formula can be rearranged: \( V_1 = \frac{C_2 \times V_2}{C_1} \) or \( V_2 = \frac{C_1 \times V_1}{C_2} \).

Q3: Does this work for serial dilutions?
A: For serial dilutions, you need to apply the formula sequentially for each dilution step.

Q4: Are there limitations to this formula?
A: This formula assumes ideal mixing and that the solute volume doesn't significantly contribute to the final volume (valid for most dilute solutions).

Q5: Can I use this for percentage solutions?
A: Yes, the formula works for any concentration units as long as C1 and C2 use the same units.
