Which is the best definition of a buffer solution?
Buffer Solutions A buffer solution is one in which the pH of the solution is “resistant” to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base, in relatively equal and “large” quantities.
What does it mean when your computer has a buffer?
Most people have a general idea of the term “buffer” in computing: a region in memory used for temporarily storing data before transferring it to another location. For example, you may see the message “buffering” when watching an Internet video, which indicates that the computer is waiting for the buffer to be filled before continuing playback.
How is a queue used as a buffer?
In many cases, the queue is used as a data buffer in some hardware interrupt service routine. This buffer will collect the data so that at some later time another process can fetch the data for further processing. This use case is the single process to process buffering case.
What is the definition of a ring buffer?
The ring buffer is a circular software queue. This queue has a first-in-first-out (FIFO) data characteristic. These buffers are quite common and are found in many embedded systems.
What happens when a strong base is added to a buffer?
When a strong base (OH -) is added to a buffer solution, the hydroxide ions are consumed by the weak acid forming water and the weaker conjugate base of the acid. The amount of the weak acid decreases while the amount of the conjugate base increases.
How do you calculate the pH of a buffer system?
By knowing the K a of the acid, the amount of acid, and the amount of conjugate base, the pH of the buffer system can be calculated. In order to calculate the pH of the buffer solution you need to know the amount of acid and the amount of the conjugate base combined to make the solution.
What does the buffer capactity mean in chemistry?
The buffer capactity refers to the maximum amount of either strong acid or strong base that can be added before a significant change in the pH This is simply a matter of stoichiometry. amount of strong acid that can be added is equal to the amount of conjugate
