🧪 Dilution Formula Explained

C₁V₁ = C₂V₂

The moles of solute before and after dilution are equal. Only the volume changes when you add solvent.

  • C₁ = initial (stock) concentration
  • V₁ = volume of stock solution taken
  • C₂ = final (diluted) concentration
  • V₂ = total final volume

📖 Example

✅ Lab Problem

Dilute 50 mL of 2 M HCl to 0.5 M. What volume do you need?

C₁V₁ = C₂V₂ → 2 × 50 = 0.5 × V₂

V₂ = 100 / 0.5 = 200 mL

Add 150 mL of water to 50 mL stock solution.

❓ FAQ

What does dilution mean?
Dilution means adding solvent (usually water) to a solution to decrease its concentration. The amount of solute stays the same.
What is a dilution factor?
Dilution factor = V₂/V₁ = C₁/C₂. A 1:4 dilution means 1 part stock + 3 parts solvent = 4 parts total.

Always verify your input units before calculating. Mismatched units (e.g., using mL instead of L) are the most common source of error when determining Dilution!

Common Applications

  • Academic Study: Verifying manual homework calculations.
  • Laboratory Practice: Standardizing lab reagent preparations.
  • Data Validation: Cross-checking experimental data analysis.

Relying solely on the calculator without understanding the underlying formula. Always review the step-by-step breakdown to internalize the mechanics.
