Question

A procedure is conducted to observe the buffering capacity of a sodium acetate/acetic acid solution at pH=4.5. Consider the errors that may occur during this procedure and determine whether each error would affect the pH (or apparent pH) of the buffer solution, the buffering capacity of the solution, both values, or neither value.

A procedure is conducted to observe the buffering capacity of a sodium acetate/acetic acid solution at pH-4.5. Consider the errors that may occur during this procedure and determine whether each error would affect the pH (or apparent pH) of the buffer solution, the buffering capacity of the solution, both values, or neither value Buffering capacity pH/apparent pH and buffering capacity pH/Apparent pH Neither The pH meter The overall solution molarity A 0.01 M buffer solution is correct, but the ratio ofis prepared instead of before being used. sodium acetate to acetic acid a 0.1 M buffer solution. is not calibrated concentrations is off by 5%. Acetic acid is unavailable, so formic acid and sodium acetate are used to prepare the buffer. The pH probe is not rinsed after calibration with the pH=7 standard solution
