5. Quantifying the Effect of Inorganic Salts on Aqueous Solubility and Aqueous Activity Coefficient (SGI 2017) Draw phenanthrene and n-hexane and give me one interesting fact about each (include source). c. b. Estimate the solubility and the activity coefficient of phenanthrene in (i) seawater at 25 °C and 30% salinity and (ii) a salt solution containing 117 g NaCl per liter water. At oil exploration facilities, it is common practice to add salt to the wastewater to decrease solubility of oil components, although then the wastewater treatment has to cope with the salt problem. Calculate how much NaCl you have to add to 1 m³ of water in order to decrease water solubility of n-hexane by a factor of 10. How much Na2SO4 would roughly be required to do the same job as the NaCl (assume a factor of 3 time larger K for Na2SO4 compared to NaCl). MM Tm Im -log(Csat Log(p* (25°C) K$ (Setschenow Coeff.)
