Acids and bases are very important for life!

Basic Properties:

• Acids: They taste sour, can damage things, and turn blue litmus paper red.
• Bases: They taste bitter, feel slippery, and turn red litmus paper blue.

Examples in Biology:

• Stomach Acid: Hydrochloric acid is found in our stomachs and helps break down food.
• Baking Soda: This is a common base that can help balance out acids in our bodies.

pH Scale:

• The pH scale goes from 0 to 14.
• Acids have a pH less than 7, while bases have a pH greater than 7.
• A pH of 7 is neutral, like pure water.

Learning about acids and bases helps us understand how living things keep everything in balance!
