1. What is 10% Bleach Dilution?

A 10% bleach dilution is a common disinfectant solution made by mixing 1 part household bleach (typically 5-6% sodium hypochlorite) with 9 parts water. This creates a solution with approximately 0.5% sodium hypochlorite concentration, effective for most disinfection purposes.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Volume\_bleach} \) — Volume of concentrated bleach needed (mL)
• \( \text{total} \) — Total desired volume of diluted solution (mL)

Explanation: For every 100 mL of final solution, you need 10 mL of concentrated bleach and 90 mL of water.

3. Importance of Proper Dilution

Details: Proper bleach dilution is crucial for effective disinfection while minimizing potential damage to surfaces and reducing health risks from excessive chlorine exposure.

4. Using the Calculator

Tips: Enter the total volume of diluted bleach solution you need in milliliters. The calculator will show how much concentrated bleach and water to mix.

5. Frequently Asked Questions (FAQ)

Q1: What concentration is household bleach?
A: Most household bleach contains 5-6% sodium hypochlorite. Check the label for exact concentration.

Q2: How long is diluted bleach effective?
