HOCL is added to water in a tank as a disinfectant. After equilibrium is reached it is found that the pH of the water in the tank is 8.2 and the gas phase partial pressure is the head space of the tank is 0.2E-7 atm. (Note: Henry's law constant for HOCL = 660/atm
Find: What is the concentration of ocl- (moles) in the tank solution?
