Homework Statement
What's a buffer?
Homework Equations
The most general definition is that a buffer resists changes in pH. However, my textbook and ChemWiki by UC Davis maintain that a buffer is composed of conjugate pairs (i.e. a base and its conjugate acid).
The Attempt at a Solution
Is a buffer necessarily composed of its base and its conjugate acid or acid and its conjugate base?
I think no ... can't some salts be buffers? Such as ammonium sulfate?
