Look around you and every liquid you see will probably be either an acid or a base. The only exception would be distilled water. Distilled water is just water. Most water you drink has ions in it. It is those ions which make something acidic or basic. (alkaline)
1. Scientist use something called the “pH” scale to measure how acidic or basic a liquid is. (base also known as ALKALINE)
2. The scale goes from “0” to “14”3. Distilled water is 7 (in the middle)4. Acids are found between “0” and “6.9”5. Bases are from “7.1” to “14”6. Most of the liquid you find every day have a pH
near “7”, either a little below or a little above.
The pH scale we talk about is actually a measure of the number of H+ ions in a solution.
ACID BASE
ION: A positively or negatively charged particle
7
NEUTRAL 0-6.9 7.1-14
pH Scale:
Measures the # of H+ ions in a solution (Potential Hydrogen Ions)

pH Scale
Acid
Base
Corrosive
What is it? Scale Range? Neutral on this scale is identified by what #?
What is the # range? What kind of Ions? What colors are associated w/Acids on pH paper?What is the # range? What kind of Ions? What colors are associated w/Bases on pH paper?
