1 SUMMARY In this experiment we investigated the adsorption isotherm of acetic acid on the surface of charcoal/carbon. Different concentrations of activated carbon/charcoal from 0.3M to 0.5M were used to determine the accurate/approximate isotherm for the adsorption. The isotherm that were investigated are the BET isotherm, Langmuir isotherm, Freundlich isotherm. If the graph of the isotherm is a linear relationship between the number of moles and concentration, the theoretical isotherm is accepted/applicable. Graph 3 which is the Freundlich is the only graph that had a linear relationship between logc and log n with a correlation coefficient of R 2 = 9091 hence the isotherm was applicable. The BET and Langmuir isotherms didn’t show a linear relationship hence the isotherms were not applicable RESULTS BEFORE ADSORPTION [CH3COOH] MASS OF CARBON TRIAL 1 TRIAL 2 TRIAL AVERAGE 0.03 1.04560 6.67 6.63 6.65 0.06 1.02320 14.00 14.12 14.06 0.12 1.00550 28.43 28.53 28.48 0.2 1.00800 9.98 10.00 10.01 0.3 1.00200 14.64 14.70 14.81 0.4 1.00700 19.35 20.13 19.55 0.5 1.02730 24.00 25.16 24.51 AFTER ADSOPTION [CH3COOH] MASS OF CARBON TRIAL 1 TRIAL 2 TRIAL AVERAGE 0.03 1.04560 4.31 4.28 5.35 0.06 1.02320 10.62 10.52 12.01 0.12 1.00550 24.79 29.79 26.42 0.2 1.00800 8.76 8.68 8.72 0.3 1.00200 13.42 13.86 13.39 0.4 1.00700 17.73 17.83 17.78 0.5 1.02730 22.46 22.26 22.36 Table 1: table showing equilibrium concentration of acetic acid before and after adsorption Carbon (grams) [Acetic Acid] initial (mol.dm -3 ) (Ci) [Acetic Acid] equilibrium (mol.dm -3 ) (C) Moles of [CH3COOH] per gram of Carbon adsorbed (n) 1 1.04560 0.0267 0.0215 0.00052 2 1.02320 0.0566 0.048 0.00086 3 1.00550 0.1147 0.1064 0.00083 4 1.00800 0.1989 0.1732 0.00257 5 1.00200 0.2944 0.2660 0.00284 6 1.00700 0.3885 0.3533 0.00352

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
