You don't. It is a trick question, write "NH 72 " which will show how it is insolutionable.

Decide on the concentration of the buffer, use 1L to be simple PH for your buffer should be within one pH unit from the pKa of the acid/conjugate base use Henderson Hasselbalch Equation pH = pKa + log ([Base]/[Acid]) For a 1 M buffer [Acid] + [Base] = 1

pay more attention in class. pH = pKa + log [A-]/[HA Im not helping you anymore
the pH of whole fat butter (72-86% fat) is 4.1-4.6 mainly because FFA.
You prepare 0.05mM from NaHC03 by first dissolving it. As you dissolve it in water, monitor the pH of the solution. The Internet does not list anything with the formula ZnSO4.7H20.
