In laboratory work, diluting concentrated stock solutions to create working solutions is a common task. Ensuring correct dilution is essential for experiments, research, and chemical analysis. Manual calculations can be confusing and prone to error.
Our Stock Dilution Calculator on our website simplifies this process by accurately calculating the volumes of stock solution and diluent needed for any desired dilution. It’s designed for students, researchers, lab technicians, and professionals who need precise results every time.
What Is a Stock Dilution Calculator?
A Stock Dilution Calculator is a tool that helps you prepare diluted solutions from concentrated stock solutions using the standard dilution formula. It ensures:
- Correct solution concentration
- Accurate volume measurement
- Safe and efficient lab work
Required Inputs
To use the Stock Dilution Calculator, you need:
- Stock solution concentration (C1)
- Desired working solution concentration (C2)
- Total volume of working solution (V2)
These inputs are essential; no unnecessary fields are required.
Expected Outputs
The calculator provides:
- Volume of stock solution needed (V1)
- Volume of diluent required (V2 − V1)
Formula Used
The calculation uses the standard dilution formula:
C1 × V1 = C2 × V2
Where:
- C1 = concentration of stock solution
- V1 = volume of stock solution required
- C2 = desired concentration of working solution
- V2 = total volume of working solution
From this formula:
V1 = (C2 × V2) ÷ C1
Diluent volume = V2 − V1
This ensures accurate preparation of working solutions.
How to Use the Stock Dilution Calculator
Step 1: Enter Stock Concentration
Input the concentration of your stock solution (e.g., 5 M).
Step 2: Enter Desired Working Concentration
Input the target concentration (e.g., 1 M).
Step 3: Enter Total Volume
Specify the total volume of working solution needed (e.g., 250 mL).
Step 4: Click Calculate
The calculator displays the required stock solution volume and the volume of diluent.
Practical Example
Suppose you have:
- Stock solution: 6 M
- Desired working solution: 2 M
- Working solution volume: 300 mL
Calculate stock solution volume:
V1 = (C2 × V2) ÷ C1
V1 = (2 × 300) ÷ 6
V1 = 600 ÷ 6
V1 = 100 mL
Calculate diluent:
Diluent = V2 − V1 = 300 − 100 = 200 mL
You will need 100 mL of stock solution and 200 mL of diluent.
