Dilute Calculator

Preparing solutions at the correct concentration is crucial in chemistry, biology, and laboratory work. The Dilute Calculator is a professional, user-friendly tool that helps students, researchers, and lab technicians determine how to dilute a concentrated solution to a desired concentration efficiently and accurately.

How to Use the Dilute Calculator

Required Inputs:

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

Expected Outputs:

• Volume of stock solution needed (V1).
• Volume of solvent to add to achieve the desired dilution.

Calculation Logic:
The Dilute Calculator 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 required
• $C_2$C2​ = desired final concentration
• $V_2$V2​ = final solution volume

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

The volume of solvent to add = $V_2 - V_1$V2​−V1​.

Step-by-Step Instructions

1. Enter the initial concentration (C1).
2. Enter the desired final concentration (C2).
3. Enter the final solution volume (V2).
4. Click calculate to see:
   • Volume of stock solution required (V1)
   • Volume of solvent to add
5. Mix the stock solution with the solvent according to the calculated amounts.

Practical Example

Suppose you have a 10 M stock solution and want to prepare 200 mL of 2 M solution:$$V_1 = \frac{C_2 \times V_2}{C_1} = \frac{2 \times 200}{10} = 40 \text{ mL}$$V1​=C1​C2​×V2​​=102×200​=40 mL

• Use 40 mL of the stock solution.
• Add 160 mL of solvent to reach 200 mL of 2 M solution.
