1a. What pH did you get for the 1.0M HCl?

Removed: 3d2

1b. From your calculation, did you get the same molarity as stated on the container?

Removed: 5d3

1c. What pH did you get for 1.0M HC₂H₃O₂?

Removed: 7d4

1d. From your calculation, did you get the same molarity as stated on the container?

Removed: 9d5

1e. If both solutions are 1.0M, why would they not have same (or close to) pH readings? Explain why they were different?

Removed: 12d7

2a. What pH did you get for the 1.0M NaOH?

Removed: 14d8

2b. From your calculation, did you get the same molarity as stated on the container?

Removed: 16d9

2c. What pH did you get for 1.0M ammonia water (NH₄OH solution)?

Removed: 18d10

2d. From your calculation, did you get the same molarity as stated on the container?

Changed: 20c12

2e. If both solutions are 1.0M, why would they not have same (or close to) pH readings? Explain why they were different?

2. Look at the pH of the 1.0M NaOH solution and then look at the pH of the 1.0M ammonia water (NH₄OH solution) solution. If they both have the same molarity (1.0M), why are the pH not the same or close to the same? Explain.
