3. The Henderson-Hasselbalch equation can be written for a base instead of an acid: A student needs to create a buffer of pH 9.8. a) What would the pOH of this buffer be? b) Which base, carbonate or pyridine would be best to use for this buffer? Why? c) What is the ratio of [Acid]/[Base] necessary to create a buffer of this pH? d) What mass of the base you chose is required to prepare half a liter of this buffer with an [Acid] =1.50 M? e) Which would have a higher buffer capacity, a buffer built to have an [Acid] of 1.50 M or one to have a [Base] of 1.50 M? Why?
