Physiological pH = 7.365 which is a basic pH.
At basic pH molecules will be prodeominantly in it's basic state, in this case NH3. Nevertheless, pKa = 9.3, and pH is 2 points below pka, the predominating species is the acidic form, NH4+

Ammonia exists in two forms, ammonium ion (NH4+) and ammonia gas (NH3). In solution, they are related by the reaction Nh4=H+NH3 pK=9.24 If the pH is 8.5 and the total ammonia concentration (ct) is 40 mg/L as N, calculate the concentration of dissolved ammonia gas (NH3) concentration id mg/L (Answer is 7.33 mg/L )

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?

Ammonia, NH3, is a weak base because a proton can readily bind to the lone pair on the nitrogen to produce the ammonium ion, NH4+. Organic compounds that contain nitrogen are also weak bases for the same reason. Amines are compounds derived from ammonia in which one or more of the hydrogens are replaced by a carbon-containing group (R). The simplest amine is methylamine in which is a "methyl" group, CH3. Its kb is 4.4 X 10-4. Write the balanced...
