The addition of 0.010 moles of sodium hydroxide to a 1.0 L solution of a buffer which is 1.0 M in acetic acid and 1.0 M in sodium acetate would shift the pH from 4.74 to _________.
A buffer ceases to function in pH regulation once one of the components is ___________.
The addition of a strong acid/base to a buffer system produces a situation where [H3O+] has changed, and so ___________.
The amount of strong acid or base a buffer can neutralize without large pH change is called its ____________.
Preparation of a buffer of specific pH is usually accomplished by creating a specific molarity of the acid or base solution, then adding the conjugate salt as a _____________.
