for ethanoic acid is 1.8 x in pure water. A) Calculate percent error of the K, you determined to this standard value. % Error : =Theoretical Value - Experimental Value Theoretical Value X 100 B) Suppose that you used an indicator that fell in the buffer zone of the titration curve. Explain how the source of error either increased or decreased the Ka that was derived from experimental data.

Transcribed Image Text:2. At SATP, the theoretical K, value for ethanoic acid is 1.8 x 105 in pure water.
A) Calculate percent error of the K, you determined to this standard value.
% Error Theoretical Value - Experimental Value
Theoretical Value
X 100
B) Suppose that you used an indicator that fell in the buffer zone of the titration curve. Explain how the
source of error either increased or decreased the Ka that was derived from experimental data.
3. Based on your results, calculate the pH of the solution at equivalence point. Comment on this pH (i.e. why
is it neutral, acidic, or basic). Remember the K, = 1.8 x 105.
