Final answer:
In a collection of more than two buffers, each unit is part of a buffer system which resists pH changes in a solution. These buffers have a limit, known as buffer capacity, which determines how much acid or base they can neutralize without significant pH change.
Step-by-step explanation:
When more than two buffers are used, the collection of buffers is itself referred to as a buffer system, with each individual buffer being one unit. Buffer systems are crucial in maintaining the pH level in various chemical and biological contexts.
Buffer solutions are a mixture designed to resist changes in pH when small amounts of acid or alkali are added. A buffer solution works effectively within a certain limit of acid or base addition; beyond this limit, known as the buffer capacity, the solution can no longer resist significant pH changes.
Buffers more robust in solute concentration offer larger buffer capacities, indicating their enhanced ability to neutralize added acids or bases without altering the pH substantially.
When more than two buffers are used, the collection of buffers is itself referred to as a buffer system, with each individual buffer being one unit.
Buffer solutions are mixtures that can resist changes in pH upon the addition of small amounts of acid or base. These solutions have a certain buffer capacity, which is the amount of acid or base that can be added before the pH changes significantly.
