Data Analysis and Conclusions

 

                To achieve the initial molar conductivity and Ka for acetic acid the above tables were created. The data from this table was then used to create a plot of the inverse of the molar conductivity  against the molar conductivity time the concentration of the solution. From this graph the initial molar conductivity and Ka was calculated.

 

 

The initial molar conductivity is equal to the inverse of the slope and the equilibrium constant is equal to the inverse of the square of the initial molar conductivity times the slope. The initial molar conductivity of glacial acetic acid was determined to be 145.60 and the equilibrium constant was determined to be 1.33x10-7. The actual value of the equilibrium constant is accepted to be 1.80x10-5. This causes our experimental value to have a percent error of 99.26. This is a very large error indicating something went wrong in the experiment. The conductivity probe had a small hole on its side in which the solution was to enter while the probe was submerged. It is likely that the hole was not filled and the readings were not accurate. This would account for the large amount of error. Two ways to alter the lab for better results could be to use two probes and take the average of their readings, or to introduce more dilutions for testing. Overall the experiment resulted in too large of a percent error to be considered a valuable prediction of the equilibrium constant and molar conductivity of acetic acid.
