What is Adsorption of Oxalic Acid on Charcoal about?

1. The experiment aimed to demonstrate oxalic acid adsorption on activated carbon in an aqueous solution and verify the Freundlich isotherm hypothesis. 2. Four samples with different oxalic acid concentrations were prepared and 1 gram of activated carbon was added to each. The samples reached equilibrium after 30 minutes of shaking. 3. Concentrations were determined through titration with potassium permanganate. A graph of log(C) versus log(x/m) produced a linear relationship, allowing determination of
