1. What is the Dilution Equation?

The dilution equation (C1 × V1 = C2 × V2) describes the relationship between concentrations and volumes before and after a dilution. It's based on the principle of mass conservation, where the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C1 \) — Initial concentration (mol/L)
• \( V1 \) — Initial volume (L)
• \( C2 \) — Final concentration (mol/L)
• \( V2 \) — Final volume (L)

Explanation: The equation states 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, medicine, and many industrial processes for preparing solutions of desired concentrations from stock solutions.

4. Using the Calculator

Tips: Enter any three known values (leaving one field empty) to calculate the missing variable. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units with this calculator?
A: The calculator uses consistent units (mol/L for concentration, L for volume). Convert your values to these units before calculation.

Q2: What if I get a negative result?
A: The calculator will only return positive results. Negative inputs are automatically converted to positive.

Q3: How precise are the calculations?
A: Results are rounded to 4 decimal places for practical use, but maintain higher precision during calculation.

Q4: Can this be used for serial dilutions?
A: This calculates single-step dilutions. For serial dilutions, you would need to perform multiple calculations.

Q5: Does this account for volume changes due to mixing?
A: The equation assumes ideal behavior where volumes are additive. For very precise work, consider actual measured volumes.
