Dilution Ratio Calculator

How to Use the Dilution Ratio Calculator

1. Enter the Initial Concentration (C₁) of your stock solution (e.g., 2.0 M).
2. Enter the Final Concentration (C₂) you want to achieve (e.g., 0.5 M).
3. Enter the Initial Volume of Stock Solution (V₁) you are starting with (e.g., 100 mL).
4. Click the Calculate button to determine the required final volume and solvent volume.
5. The calculator will display the Final Volume of Diluted Solution (V₂) and the Volume of Solvent to Add (V₂ - V₁).

Working Principle

The calculator uses the formula C₁V₁ = C₂V₂, which is based on the principle of conservation of solute. When you dilute a solution, the amount of solute remains constant, but the total volume increases. The formula helps determine how much solvent to add to achieve the desired concentration.

Example

Suppose you have 100 mL of a 2.0 M NaCl solution and you want to dilute it to 0.5 M. Using the calculator:

• C₁ = 2.0 M
• V₁ = 100 mL
• C₂ = 0.5 M
• V₂ = (2.0 M × 100 mL) / 0.5 M = 400 mL
• Volume of solvent to add = 400 mL - 100 mL = 300 mL

Applications

This calculator is useful in various fields including:

• Laboratory experiments
• Chemistry and pharmaceutical research
• Biology and medical applications
• Industrial processes requiring precise concentration control
