1. Notes: Acids and Bases

2. Acids taste sour conduct electricity
Note: NEVER taste an acid in class!
conduct electricity
react with indicators to produce predictable changes in color
corrode metals (HCl Acid corrodes Mg ribbon)

3. Common Acids
Sulfuric Acid
Hydrochloric Acid
Nitric Acid
Citric Acid

4. In solution, feel slippery (like soap) corrode metals
Bases
Bitter taste
In solution, feel slippery (like soap)
corrode metals
conduct electricity
React with indicators

5. Common Bases
Aluminum Hydroxide
Calcium Hydroxide
Ammonia

6. What is the pH scale? 1-6 for an Acid (1 is the strongest acid)
7- Neutral (water is a neutral substance)
8-14 for bases (14 is the strongest base).

7. pH Scale

8. Vocabulary
Indicators such as litmus, pH paper, and cabbage juice are used to detect the presence of acids and bases by changes in color.
Reactivity is the tendency of a substance to undergo chemical reaction, either by itself or with other materials.
Combustibility, or flammability, means that a substance is capable of igniting and burning.

9. What is a neutralization reaction?
Neutralization: a chemical reaction between an acid and a base which produces water and salt
During a neutralization reaction…
hydronium ion, H+ (acid) + hydroxide ion, OH- (base) = water
negative ions (acid) + positive ions (base) = salt
Acid + Base = Water + Salt
