With this how I calculate the Ammonia solutions pH and Ammonia Buffer solutions ph B. Preparation of Ammonia-Ammonium Buffer Solution Note that an ammonia buffer contains the conjugate base, ammonia, and its conjugate acid, the ammonium ion, NH typically added as NH,CI. Accordingly, the pk, value stated in Eq. (7) is that of the buffer's conjugate acid, NH.. For ammonia, pk, -log (1.8 x 107 4.74. (Note that the fact that the pk for NH, is the same value as...
