Abuffer is generated using nh3 and nh4cl. which of the following is true?
a.) any buffers generated for which [nh3]/[nh4cl] is the same will have identical ph
b.) if [nh3]=[nh4cl], the ph will equal the pka for nh3
c.) any buffers generated for which [nh3]/[nh4cl] is the same will have an identical buffering capacity
d.) if [nh3]/[nh4cl] in buffer 1 is greater than buffer 2, then buffer 1 will have a greater buffering capacity
