1. What is the Alcohol Dilution Formula?

The alcohol dilution formula (C1V1 = C2V2) is used to calculate how to dilute a high-concentration alcohol solution to a desired lower concentration by adding a specific amount of water.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C1 \) — Initial concentration (%)
• \( V1 \) — Initial volume (mL or L)
• \( C2 \) — Desired concentration (%)
• \( V2 \) — Final volume after dilution (mL or L)

Explanation: The formula maintains that the amount of pure alcohol remains constant before and after dilution.

3. Importance of Proper Dilution

Details: Accurate dilution is crucial for preparing disinfectants, laboratory solutions, and beverages with precise alcohol concentrations.

4. Using the Calculator

Tips: Enter initial concentration (%), initial volume (with unit), and desired concentration (%). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for any liquid dilution?
A: Yes, the formula works for any solution where you're diluting with a solvent (like water) that doesn't contain the solute.

Q2: What if I want to make a larger batch?
A: Simply scale up all volumes proportionally while maintaining the same concentration ratios.

Q3: Does temperature affect the calculation?
A: The calculation assumes volumes are additive at the same temperature. For precise work, account for temperature effects on volume.

Q4: How accurate is this for high-proof alcohol?
A: Very accurate for typical dilutions. For extremely high concentrations (>90%), small deviations may occur due to non-ideal mixing.

Q5: Can I calculate reverse dilution?
A: Yes, the same formula can determine how much concentrated solution to add to achieve a desired concentration.
