1. Complete "Concept Questions for Chemistry PhET":
- The color of a solution identifies if it is an acid base, or neutral solution.
- A. True
- B. False - pH determines if it's a base, acid, or neutral
- C. Pink are base and clear are acid
- Which solution is basic?
- A. Milk
- B. Blood
- C. Custom at pH =12
- D. More than one (B &C) are basic- they are both above a pH of 7 which makes them basic.
- E. None
- Which Solution is acidic?
- A. pH=13
- B. pH = 7
- C. pH = 2- The high level makes it acidic
- D. More than one
- E. Difficult to tell.
- Which solution is basic?
- A. Water pH = 7
- B. pH = 13 -
- C. Soda = 2.5
- Which solution is acidic?
- A. Coffee = pH 5
- B. Soda = 2.5
- C. pH = 13
- D. More than one (both A and B) are acidic
- E. None
- How will adding water effect the pH?
- B. Decrease the pH
- C. No pH change.
- How will equal amount of water effect the pH?
- A. Increase the pH
- B. Decrease the pH (More water less the basicity, so the pH goes down)
- C. The pH will be cut in half
- D. No pH change
- What is the order from most acidic to most basic?
- A. ABC - The lower the pH, the higher the acidity.
- B. ACB
- C. BAC
- D. CBA
- E. CAB
- What is the order from most acidic to most basic?
- A. ABC
- B. ACB
- C. BAC- the lower the pH, the higher the acidity.
- D. CBA
- E. CAB
- If spit has a pH of 7.4, what does that tell you about the water equilibrium?
- A. Something was added that made the equilibrium shift left-
- B. Something as added that made the equilibrium shift right
- C. pH has nothing to do with the water equilibrium
- A. increase the pH (More water lessens the acidity, so the pH goes up)

I love learning about the pH scale! Did you enjoy it as well? Where you surprised by the that pH of coffee was higher than soda? I also enjoy the layout you used for activity it is close to mine.
ReplyDeleteAlyssa, great job organizing this post! I really like how you wrote all 3 of the choices for each question and then bolded the correct answer. It was also really nice how you wrote your reasoning behind why you picked the answer you did. I compared your responses to my own and we had a lot of the same answers! Also, great job on the worksheet! It was very organized and your data was very similar to my own!
ReplyDeleteGreat job at your organization, that's awesome. I liked how you explained the correct answer. It really shows your understanding of these questions.
