Acids, Bases, and pH in Everyday Life

What Are Acids and Bases?

Acids donate H⁺ ions; bases accept them. The pH scale (0-14) measures how acidic or basic a solution is.

pH in the Real World

  • Stomach acid helps digest food (very acidic, low pH).
  • Soap is basic (high pH) and helps break down grease.

Why It Matters

Understanding acids, bases, and pH keeps swimming pools clean, helps plants grow, and even prevents tooth decay!

More Cool Uses

  • Environmental scientists monitor lake pH to protect wildlife.
  • Farmers adjust soil pH for better crops.

Examples

  • Lemon juice is an acid that can clean tarnished metal.

  • Baking soda (a base) neutralizes odors in your fridge.
