Un-ionized ammonia (NH3) is toxic to fish at low concentrations. If the maximum allowable concentration of NH3 in a river (CNH3) is 0.20 mg/L as N, what is the maximum concentration of ammonium ion (NH4+) allowed (CNH4+), in units of mg/L as N, when the river water pH is 9? The dissociation of ammonium ion in water has an equilibrium constant of pKa = 9.25 and is described by the reaction: NH4+ = NH3 + H+. Show units throughout the...
