4. Properties of Acids
Many common items contain acids. Acids are compounds with specific characteristic properties.
Has more hydrogen atoms
Reacts with metals
Reacts with carbon (seashells, eggs, chalk, limestone)
Turns pH paper red, orange, and yellow
Corrosive- able to break down other substances
Tastes sour (lemons, grapefruit, oranges, vinegar, tomatoes)

5. Properties of Bases
Many common items contain bases. Bases are often described as having properties opposite of acids.
Has more hydroxide molecules
Doesn't react with metals
Turns pH paper green, blue, and purple
Feel slippery (soaps, detergents, shampoo)
Tastes bitter (melons, almonds, cocoa beans)

6. (Basic)
To determine the strength of an acid or base, chemists use a scale called pH. It ranges from The most acidic substances are found at the low end of the scale (0-6). The most basic substances are found at the high end (8-14). A pH of 7 represents an item that is neither acid or base- neutral. Ex: water

7. (Basic) Neutralization- A reaction between an acid and a base.
After mixing an acid with a base, the mixture is not as acidic or basic as the individual starting solutions were. The reaction may even result in a neutral solution. The final pH depends on the concentrations and strengths of the reactants. For example, a small amount of a strong base reacts with a very large amount of strong acid. The solution will remain more acidic, but closer to neutral than the original pH.
