Understanding Solution Dilution
Dilution is a common laboratory practice to achieve a desired concentration of a solute by adding solvent. There are two primary methods:
- Simple Dilution uses the formula C₁V₁ = C₂V₂, where C is concentration and V is volume. It allows you to calculate the amount of stock solution (or solvent) needed for your target concentration/volume.
- Serial Dilution involves performing a sequence of dilutions (e.g., 1:10 dilutions in each step), often to reach very low concentrations or to create a dilution series for assays.
Common concentration units include molarity (M), millimolar (mM), micromolar (μM), mg/mL, and g/L. Volumes are typically in liters (L), milliliters (mL), or microliters (μL).
Applications: Dilutions are essential in preparing chemical standards, reagents for spectrophotometric assays, buffer preparation, and microbiological plating (CFU estimation).
🧪 Solution Dilution Calculator: Instantly Apply C₁V₁ = C₂V₂ Formula
Need to prepare a less concentrated chemical solution from a stock solution? The Solution Dilution Calculator helps you perform precise dilutions in seconds using the classic formula:
C₁ × V₁ = C₂ × V₂
Where:
- C₁ = Initial concentration
- V₁ = Volume of stock to use
- C₂ = Final (desired) concentration
- V₂ = Final volume of solution
This tool is perfect for chemistry labs, pharmaceutical prep, classroom experiments, and even home DIY chemical projects.
⚗️ What Is a Solution Dilution?
Dilution is the process of reducing the concentration of a solute in a solution, usually by adding more solvent (like water). The total amount of solute remains the same; it’s just spread across a larger volume.
Example: If you have 1M HCl and you want 0.1M, you dilute it with water until the total volume is 10 times.
🧮 How the Calculator Works
The calculator uses the universal dilution formula:
C₁V₁ = C₂V₂
You can solve for any one unknown:
- How much of the stock solution to use (V₁)?
- What concentration you’ll get after dilution (C₂)?
- What total volume you need to prepare (V₂)?
✅ Input Options:
| Parameter | Description |
|---|---|
| C₁ | Initial (stock) concentration |
| V₁ | Volume of the stock solution used |
| C₂ | Final desired concentration |
| V₂ | Final total volume needed |
🧫 Common Use Cases
| Application | Use |
|---|---|
| 👩🔬 Chemistry Lab | Preparing specific molarities for experiments |
| 💊 Pharmacy | Diluting medications safely |
| 🌱 Agriculture | Creating correct pesticide/fertilizer solutions |
| 🧪 School Projects | Standard chemical preparations |
| 🧼 Cleaning Solutions | Adjusting disinfectant concentrations |
🧪 Example Calculation
Say you want to prepare 200 mL of 0.5M NaCl from a 2M stock solution:
Use:
C₁ = 2M
C₂ = 0.5M
V₂ = 200 mL
Solve for V₁:
V₁ = (C₂ × V₂) / C₁ = (0.5 × 200) / 2 = 50 mL
So, use 50 mL of stock solution and add 150 mL of water.
