What is an ACID?An ACID is a Compound that has Hydrogen at the Beginning of its
formula
HCl H2SO4 HNO3
What's a BASE ?
- Opposite of an ACID
- Used to Neutralize and
ACID
- Formula ends with -OH
Examples of Acids:
Here’s what you should know about acids:
•Can burn your skin
•React with metals
•Can damage
building materials

How do we Measure ACID or BASE ?
pH Scale

ACIDS vs. BASES
Baking Soda
Alka-Seltzer
Vinegar
Calcium Carbonate (TUMS, Rolaids)
Orange Juice
Lemon Juice
Let's Sort These:

ACID Rain
When pollutants combine with water they make acid rain, rain that is acidic (pH<5.5)

Acid / Base Review
Term DefinitionBegins with an H
BASE0-14 (7 is neutral)
STRONG ACIDSRain w/ pH <5.5
SO, NO pollutants
