What Is Dilution?

Dilution is the process of reducing the concentration of a solution by adding more solvent. It is commonly used in:

• Chemical experiments
• Biological assays
• Pharmaceutical preparations

How the Calculator Works

The tool is based on the standard dilution formula:

C₁ × V₁ = C₂ × V₂

Where:

• C₁ = Initial concentration
• V₁ = Initial volume
• C₂ = Final concentration
• V₂ = Final volume

---

Required Inputs:

• Initial concentration (C₁)
• Final concentration (C₂)
• Final volume (V₂)

Output:

• Required initial volume (V₁)

How to Use the Tool

1. Enter the initial concentration.
2. Enter the desired final concentration.
3. Enter the final volume.
4. Click calculate.
5. Get the required volume of stock solution.

Practical Example

If you have:

• C₁ = 10 mg/mL
• C₂ = 2 mg/mL
• V₂ = 100 mL

Calculation:

V₁ = (C₂ × V₂) / C₁
V₁ = (2 × 100) / 10 = 20 mL

You need 20 mL of stock solution and dilute it to 100 mL.
