Class Notes Topic: ________________________ Name ________________________________________ Class ________________________________________ Period ________________________________________ Date _____________________________________ Notes: Acids and Bases 1. What is an ION? 2. Why is an atom “charged”? 3. What is pH? 1. A positively or negatively charged atom. 2. It has more or less electrons than protons. 3. pH stands for potential of Hydrogen Ions

5. What types of substances do these Ions form? 5. More H+ particles in a solution make an ACID More OH- particles in a solution make a BASE 4. What types of Hydrogen Ions are there? 4. There are positive Hydrogen (H+) ions and negative Hydrogen Ions (OH-) called Hydroxide Ions

6. What is the pH scale? 6. The pH scale tells you the strength of the acid or base. It is a scale numbered What colors are associated with Acids and Bases? 7. Ion sensitive papers or probes turn “HOT”colors (Red, Orange & Yellow) for Acids and “COOL” colors (Green, Blue, Purple) for Bases 1 = strongest acid 7 = neutral 14 = strongest base

8. Summary
