4. Activated carbon weighing 3 g was added to three solutions of acetic acid of different concentrations with a volume of 100 ml each. The amount of acid before and after adsorption was determined by titration with a KOH solution, C(KOH) = 0.1 mol/l. Determine the adsorption value for each solution using

Volume of acid taken for titration before and after adsorption, ml 50 50 50
Volume of KOH solution consumed for titration before adsorption, ml 5.5 10.6 23.0
The same, after establishing adsorption equilibrium, ml 1.22 3.65 10.20
