You are preparing a buffer with pH = 5. To prepare the
buffer you decided to calculate how much solid sodium acetate
you need to prepare and vol of 1M acetic acid. You also
decided to use pH meter after preparing buffer to confirm the
pH.
Assuming all calculations are correct, which situation will
have bigger error , uncalibrated pH electrode or uncalibrated
weighing balance ? explain your answer. Bigger error would mean an
error that would be more difficult to correct or error that would
have more impact on final pH of your solution.
