1. What is the Dilution Formula?

The dilution formula (C1 × V1 = C2 × V2) describes the relationship between concentrations and volumes before and after dilution. It's a fundamental equation in chemistry for preparing solutions of desired concentrations.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

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

Explanation: 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 for preparing standard solutions, performing titrations, and conducting experiments that require precise concentrations.

4. Using the Calculator

Tips: Enter any three known values and leave one field blank. The calculator will compute the missing value. All inputs must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units with this calculator?
A: The calculator uses mol/L for concentration and liters for volume. Convert your units to these before calculation.

Q2: Does this formula work for serial dilutions?
A: For serial dilutions, you need to apply the formula sequentially for each dilution step.

Q3: What if my final volume is larger than my initial volume?
A: This is normal for dilutions - you're adding solvent to decrease concentration while increasing volume.

Q4: Can this be used for solid dilutions?
A: No, this formula is for liquid dilutions. For solids, you would need to consider mass concentrations.

Q5: How precise are the calculations?
A: The calculations are mathematically precise, but real-world accuracy depends on measurement precision.
