contain a significant amount of a weak acid and its conjugate base (or a weak base and its conjugate acid)

2
New cards

Henderson-Hasselbalch Equation

An equation that relates the pH of a buffer solution to the initial concentration of the buffer components

3
New cards

Conjugate Base

Acid loses a proton -H (HCl →Cl-)

4
New cards

Conjugate Acid

Base gains a proton +H (NH3→NH4+)

5
New cards

Buffer Range

The pH range over which a particular acid and its conjugate base can be effective (pKa+-1)

6
New cards

Buffer Capacity

The amount of acid or base that can be added to a buffer without causing a large change in the pH

7
New cards

Acid-base titration

A laboratory procedure that an unknown concentration solution (acid or base) is reacted/titrated with solution of known concentration (acid or base)
