EQUL 499- Det. Of pH of Strong Acid, weak acid, salt, and buffer solution Discussion Topics Discussion Topics (need to submit in Blackboard): 1. What is a buffer? • A buffer is a solution that, when introduced to a new environment, undergoes minimal pH change, typically when adding acidic or basic solutions. These are extremely important for life because the pH of human blood is delicate and even if it is changed by 0.1, there may be catastrophic effects. 2....

I
know some of the measured pH values are a little off due to error
in the lab, but I need help filling out the “Ion Hydrolyzed” table
and then the “Net Ionic Equation” part. I remember doing net ionic
equations in General Chemistry I, bit don’t see how it applies
here.
Thanks, in advance! (i will rate!)

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...
