strong acids and bases as buffers
(1/1)
tiff27:
I am completely stuck on this question ??? Why is the salt of a strong acid and a strong base not a good buffer? I also am stuck on a balanced equation to represent this. I got as much as a strong acid and its salt is completley ionized and to be a buffer needs a weak acid to react with any oh- that is added. Am I correct so far? Thanks for your time!
AWK:
Buffer solutions work on the basis that strong acid (or base) replaces a weak one, or neutralizes weak base (or acid) with formation of salts (which hydrolysis can be neglected because of common ion present in buffer solution).
But in some cases HCl/NaCl can be used as buffer solution though its buffering strength is rather small.
