2nd Period, 4th Period, 5th Period: Chapter 7 Vocabulary Quiz
EYES ON YOUR OWN PAPER!!!! Cheating = 0!!!!! Copy Notes ( I will explain them Monday.) Do Worksheet “Describing Acids and Bases” (front and back) You may write on the worksheet. What you do not finish in class will be homework. I will take it up for a grade on Monday.

Bell Ringer List a property of an acid and an example of an acid. List a property of a base and an example of a base. Give an example of a pH value of the strong acid. Give an example of a pH value of a strong base. What does the pH scale tell you? What does pH stand for?
5
Acids and Bases in Solution
Chapter 7 Section 4 Acids and Bases in Solution
6
What happens if you combine a corrosive acid and a strong base?
Not much of anything!!
7
Refer to the chart on p. 243 in your book.
How do all the chemical formulas for the acids begin? They all start with Hydrogen. HCl, HNO3, H2SO4 Recall: Acids produce hydrogen ions (H+) in water.
8
Acids in water solutions separate into hydrogen ions and negative ions.
HCl ---- H+ + Cl-
9
Refer to the chart on p. 243 in your book.
What elements do a lot of the bases include? Recall: Bases produce hydroxide ions (OH-) in water.
10
When bases dissolve in water the positive ions and hydroxide ions separate.
NaOH ---- Na+ + OH-
11
Acids and bases may be strong or weak.
The strength refers to how well an acid or a base produces ions in water.
12
Examples Strong Acids Weak Acids Strong Bases Weak Bases
Hydrochloric Acid - Banana Sulfuric Acid - Acetic Acid Nitric Acid - Tomato Strong Bases Weak Bases Sodium Hydroxide - Ammonia Drain Cleaner - Baking Soda
13
pH Scale
14
pH What does pH mean????????? p = potential H = hydrogen ions
pH = the potential to attract hydrogen ions
15
In water, acids and bases separate into H+ ions or OH- ions
BASES – high potential to atract ions ACIDS – low potential to attract H ions
16
Neutralization- reaction between an acid and a base
Sometimes an acid-base reaction results in a neutral solution. In a neutralization reaction, an acid reacts with a base to produce a salt and water. Chart of Common Salts on page 247
