The pH scale is a helpful tool for understanding how acidic or basic common household items are. It goes from 0 to 14, like this:

• Acids: pH 0-6
• Neutral: pH 7
• Bases: pH 8-14

Here’s a List of Some Common Household Items and Their pH Values:

1. Lemon Juice: pH 2-3 (acidic)
2. Vinegar: pH 2.5-3 (acidic)
3. Baking Soda: pH 8-9 (basic)
4. Soap: pH 9-10 (basic)
5. Bleach: pH 12-13 (very basic)
6. Distilled Water: pH 7 (neutral)
7. Milk: pH 6.5-7 (slightly acidic)

Why pH Measurement is Important:

• Neutralization Reactions: When acids and bases mix, they can create water and salts. This is important for keeping things balanced in our daily lives.
• Safety: Knowing the pH of substances can help avoid accidents. For example, bleach (with a pH of 12-13) can hurt your skin if not handled properly.

In Summary:

The pH scale helps us identify and safely use different household products. This makes everyday tasks safer and can help us learn more about chemistry.
