What: "pH is all about the equilibrium between free hydrogen ions (technically H3O) and hydrogen bound to it's conjugate base. The more likely that a hydrogen ion will disassociate from its base, the lower it will drive the pH. With a buffer solution the amount of hydrogen ions that will associate or disassociate varies greatly over a small range of free hydrogen concentration (pH). Essentially, a buffer is like a hydrogen sponge. The hydrogen ions are still there, but if they're in the sponge, they aren't contributing to the pH."
