Term: Conjugate Acid (in a buffer)
The component of a buffer solution that reacts with any added base to stabilize pH.
What are the two essential components of a buffer?
A buffer must contain a large concentration of both a conjugate acid and its corresponding conjugate base.
What is a buffer solution?
A buffer solution contains a large concentration of both a conjugate acid and its base, which allows it to stabilize pH.
How does a buffer stabilize pH when a base is added?
The conjugate acid in the buffer solution reacts with the added base, minimizing the change in pH.
Term: Conjugate Base (in a buffer)
The component of a buffer solution that reacts with any added acid to stabilize pH.
If a strong base is introduced into a buffered solution, which component of the buffer will react?
The conjugate acid component of the buffer will react with the added base.
How does a buffer stabilize pH when an acid is added?
The conjugate base in the buffer solution reacts with the added acid, minimizing the change in pH.
Explain the relationship between a buffer's composition and its function.
A buffer's ability to stabilize pH is directly related to its composition; it must have a conjugate acid to react with added base and a conjugate base to react with added acid.
If a strong acid is introduced into a buffered solution, which component of the buffer will react?
The conjugate base component of the buffer will react with the added acid.
Why is a large concentration of buffer components necessary?
A large concentration of both the conjugate acid and base is required for the buffer to effectively neutralize added acids or bases without being depleted.
