Wastewater at 600 gpm, containing 10 ppm (by weight) of benzene, is to be stripped with air in a packed column, operating at 25∘c and 2 atm, to produce water containing 0.005 ppm of benzene. the packing is 2-inch polypropylene flexirings. the vapor pressure of benzene at 25∘c is 95.2 torr. the solubility of benzene in water at 25∘c is 0.180 g∕100g. an expert∘in voc stripping with air suggests the use of 1,000 scfm of air (60 f, 1 atm). at these conditions, for benzene,

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
