Problem:
Question 1: Did any solution change PH more after an acid was added to it than after a base was added to it ?
1) yes the water ‘s PH wasn't changed by the acid, but it dropped great deal with the addition of the base .However the other solutition reacted similar to both the acid and the base .
2) no all four soulation reacted very similar to both the acid and the base .
3) No, neither the acid nor the base changed the pH of any of the solutions.
4) Yes, the water's pH wasn't changed by the acid, but it dropped a great deal with the addition of the base. However, the other solutions reacted similarly to both the acid and the base.
Question 2: What was the pH after you added 10 drops of acid?
1) 4.5
2) 2.1
3) 6.8
4) 9.3
Question 3: After the addition of how much acid or base was the pH 9.2?
A. 12 drops of base
B. 10 drops of acid
C. 6 drops of base
D. 3 drops of acid
Question 4: How many drops were necessary for the pH to change dramatically? This number is the amount drops at which the buffer stopped maintaining a nearly constant pH of the solution. (Record your result for use in a later question)
A. up to 10 drops of acid and up to 12 drops base
B. B. up to 8 drops of acid OR base
C. C. up to 3 drops of acid and up to 6 drops base
D. D. up to 5 drops of acid OR base
Please provide correct answer.
