1. What is the Dilution Equation?

The dilution equation (C₁V₁ = C₂V₂) describes how the concentration of a solution changes when it is diluted. It's a fundamental principle in chemistry used to prepare solutions of desired concentrations.

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 after dilution (L)

Explanation: The equation maintains that the amount of solute remains constant before and after dilution, only the volume changes.

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 all values in consistent units (mol/L for concentration, liters for volume). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units with this calculator?
A: The calculator expects mol/L for concentration and liters for volume. Convert your units before entering values.

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution. The equation still works mathematically but may not represent a physical dilution process.

Q3: Does this account for volume changes due to mixing?
A: No, this assumes ideal behavior where volumes are additive. For precise work, consider non-ideal mixing effects.

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

Q5: How precise should my measurements be?
A: Precision depends on your application. Analytical work typically requires 4+ significant figures in measurements.
