Solution Dilution Calculator - Chemistry Tool

Solution Dilution Calculator

Calculate initial or final concentration, as well as required volumes, for laboratory dilutions. Choose between simple and serial dilution methods, explore different concentration units, and learn about their practical laboratory applications.

Simple Dilution

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).

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)?

🧫 Common Use Cases

ApplicationUse
👩‍🔬 Chemistry LabPreparing specific molarities for experiments
💊 PharmacyDiluting medications safely
🌱 AgricultureCreating correct pesticide/fertilizer solutions
🧪 School ProjectsStandard chemical preparations
🧼 Cleaning SolutionsAdjusting 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.
