Activity 7

1. Review the Content Slides Acids and Bases on the D2L site.


2. Complete the Teaching Idea “Concept Questions for Chemistry using PhET” posted by Trish Loeblein on the pH Scale simulation at PHET (http://phet.colorado.edu/en/simulation/ph-scale). On your blog post the answers with your scientific explanations from the “Clicker Questions pH Scale” posted by Trish.

1. The color of solution identifies if it is an acid, base, or neutral solution.
B. False, The PH scale identifies what it is.

2. What solution is basic?
Answer- D. More than one.

3. What solution is acidic?
Answer-C.

4. Which solution is basic?
B. The OH- level is higher.

5. Which solution is acidic?
Answer- D

6. How will adding water effect the pH?
A. The more water=acicidy goes down, which means pH levels go up.

7. How will equal amount of water effect the pH?
B. Decreases the pH.

8. What is the order from most acidic to most basic?
A. ABC the lower pH means the more acidic.

9. What is the order from most acidic to most basic?
C. BAC

10. If spit has a pH=7.4, what does that tell you about the water equilibrium?
A. Something was added that made the equilibrium shift left. 



3. Complete the Teaching Idea “Intro to Strong and Weak Acids and Bases” posted by Chris Bires on the Acid-Base Solutions simulation (http://phet.colorado.edu/en/simulation/acid-base-solutions) and post on your blog your data and answers to the questions posed.
