2. CORNELL NOTES SET-UP
TITLE IN THE LEFT HEADING EQ QUESTION WRITTEN ACROSS FIRST LINE ON THE LEFT PAGE DATE IN THE UPPER RIGHT HEADING SUMMARY 3-5 LINES FROM THE BOTTOM OF THE RIGHT PAGE AT THE END OF THIS LESSON, YOU WILL POSE TWO QUESTIONS THAT RELATE TO NEW INFORMATION FROM THIS LECTURE. YOU WILL ALSO WRITE A 3-4 SENTENCE SUMMARY THAT BEGINS BY ANSWERING THE ESSENTIAL QUESTION. THEN YOU WILL ANSWER THE TWO QUESTIONS YOU POSED IN YOUR “QUESTIONS” COLUMN.
The title goes on the left. The essential question is written across the first line on the left page. Split the left page into two columns: one for questions and one for notes. The date goes on the upper right corner. Go ahead and split this left page into three sections: one for questions, one for notes, and the bottom for summary. Remember to place your summary three to five lines from the bottom of the page giving yourself enough room to write three to four sentences.

3. CORNELL NOTES SET-UP TITLE: Acids and Bases DATE: 3/27/17
ESSENTIAL QUESTION: HOW ARE ACIDS AND BASES USED IN EVERYDAY LIFE?
MAKE SURE YOU HIGHLIGHT OR UNDERLINE NEW TERMS!
The title is states of matter. The essential question is “What are the states of matter?” By the end of this lecture, your goal is to demonstrate your understanding of the states of matter by summarizing Cornell Notes.

4. Acid An acid is a solution that has an excess of H+ ions
Latin means “sharp” or “sour”
The more H+ ions, the more acidic the solution

5. Properties of an Acid Tastes sour Conducts electricity
Corrosive meaning they break down certain substances
React strongly with metals
Turns blue litmus paper red
Examples include:
Lemons, limes, oranges
Vinegar
Sour candies such as Sour Patch Kids
Car batteries

6. Base A base is a solution that has an excess of OH- ions
Another word for base is alkali
Bases are substances that can accept hydrogen ions

7. Properties Feels slippery Tastes bitter Corrosive
Can conduct electricity (alkaline batteries)
Do not react with metals
Turns red litmus paper blue
Examples include:
Soaps
Ammonia
Cleaning products
Blood

8. pH Scale pH is a measure of how acidic or basic a solution is
Ranges from 0-14
Acidic solutions have pH values below 7
A solution with a pH of 0 is very acidic
A solution with a pH of 7 is neutral
Pure water has a pH of 7
Basic solutions have pH values above 7
Bleach has a pH of 12

9. DRAW THIS INTO YOUR NOTEBOOK

10. Neutralization
A reaction between an acid and a base is called neutralization
An acid-base mixture is not as acidic or basic as the individual starting solutions
If a substance has a pH of 8.0 and you want to lower the pH, you have to add acid to it.
