Dillution Calculator

In chemistry and laboratory work, achieving the correct concentration of solutions is critical. The Dillution Calculator is a professional, user-friendly tool that allows students, scientists, and lab technicians to accurately calculate dilutions. Whether you are preparing stock solutions or adjusting concentrations for experiments, this tool simplifies the process and ensures precise results.

How to Use the Dillution Calculator

Required Inputs:

1. Initial Concentration (C1) – The concentration of the starting solution.
2. Final Concentration (C2) – The desired concentration after dilution.
3. Final Volume (V2) – The total volume of the diluted solution.

Expected Outputs:

• Volume of stock solution needed (V1) to achieve the desired dilution.
• Optional step-by-step dilution instructions for lab preparation.

Calculation Logic:
The tool uses the standard dilution formula:$$C_1 \times V_1 = C_2 \times V_2$$C1​×V1​=C2​×V2​

Where:

• $C_1$C1​ = initial concentration
• $V_1$V1​ = volume of stock solution to use
• $C_2$C2​ = final concentration
• $V_2$V2​ = final solution volume

Solve for $V_1$V1​:$$V_1 = \frac{C_2 \times V_2}{C_1}$$V1​=C1​C2​×V2​​

Step-by-Step Instructions

1. Enter the initial concentration of your solution.
2. Enter the desired final concentration.
3. Enter the final volume you want to prepare.
4. Click calculate to determine the volume of stock solution needed.
5. Optionally, use the instructions to mix the solution accurately.

Practical Example

You have a 5 M stock solution and want to prepare 500 mL of 1 M solution:$$V_1 = \frac{C_2 \times V_2}{C_1} = \frac{1 \times 500}{5} = 100 \text{ mL}$$V1​=C1​C2​×V2​​=51×500​=100 mL

• Use 100 mL of the stock solution.
• Add 400 mL of solvent to achieve 500 mL of 1 M solution.
