Acids:
- pH less than 7
- Turn litmus paper red
- Taste sour
- Feel irritating/corrosive
- Examples include fruit juices, soda, and coffee
Bases:
- pH greater than 7
- Turn litmus paper blue
- Taste bitter or soapy
- Feel slippery
- Examples include baking soda, ammonia, and soap
pH scale: A scale used to measure the acidity or basicity of a substance. It ranges from 0 to 14. 7 is neutral. Numbers below 7 indicate acidity, and numbers above 7 indicate basicity.
Neutralization reaction: A reaction that occurs when an acid and a base react to form salt and water.
- Example: HCl (hydrochloric acid) + NaOH (sodium hydroxide) → NaCl (sodium chloride) + H₂O (water)
