The following solubility data were obtained for an organic compound (toluene) in the presence of humic acid extracted from a wastewater sample.
Estimate the KC for toluene on the humic acid.
It was determined that the concentration of humic acid in the wastewater pond was 20 g/m3. If the pure water Henry's constant for toluene is 0.0065 atm/m3/mol, estimate the partial pressure of toluene in the air in equilibrium with the wastewater.
