Chapter 2, Problem 53RE

MATHEMATICAL Define buffering capacity. How do the following buffers differ in buffering capacity? How do they differ in pH?

Buffer a: 0.01 M ${\text{Na}}_{\text{2}}{\text{HPO}}_{\text{4}}$ and 0.01 M ${\text{NaH}}_{\text{2}}{\text{PO}}_{\text{4}}$

Buffer b: 0.10 M ${\text{Na}}_{\text{2}}{\text{HPO}}_{\text{4}}$ and 0.10 M ${\text{NaH}}_{\text{2}}{\text{PO}}_{\text{4}}$

Buffer c: 1.0 M ${\text{Na}}_{\text{2}}{\text{HPO}}_{\text{4}}$ and 1.0 M ${\text{NaH}}_{\text{2}}{\text{PO}}_{\text{4}}$
