Experiment 3.1 Adsorption of acetic acid on to activated charcoal 

Activated charcoal or carbon is widely used for vapour adsorption and in the removal of organic solutes from water. These materials are used in industrial processes to purify drinking water and swimming pool water, to de-colorize sugar solutions as well as other foods, and to 

If we assume that the granular charcoal has a certain number of possible adsorption sites per gram (N ) and that a fraction 0 are filled by the adsorbing solute, then

measurement of N for a range of concentrations (C) should give a linear plot of C/N against C, where the slope gives the value of Nm and the intercept the value of the equilibrium constant K.
