Ammonia (NH3) is somewhat volatile. It is also the conjugate base of the ammonium ion (NH4+). In order to keep the ammonia from volatilizing from a wastewater treatment reactor, it is useful to shift this acid-base equilibrium reaction toward NH4+. The pKa of the ammonium ion is 9.24. In what pH range should the reactor operate?
