CHEM 201 Lecture Notes - Lecture 35: Buffer Solution, Conjugate Acid, Weak Base
Document Summary
Conjugate base reacts with the added acid, thus reducing the impact. Conjugate acid reacts with the added base, thus reducing the impact. *in all cases, there is still a change in the ph, but the change is. Much smaller than it would be without a buffer: no-change guideline: for a solution which begins with appreciable amounts of both members of a conjugate pair, then the shift to equilibrium will often be small. *this form is general for use with any weak acid (ha) and its conjugate base (a-), as well as for a weak base (b), and its conjugate acid (bh-) Buffer calculations are inherently more prone to non ideal behavior than simple ph calculations for just an acid or a base that"s because buffer solutions tend to involve high concentrations of ionic solutes. The change in ph will be smaller for some specific amount of acid or base to be added.
