Buffering capacity

Buffering capacity refers to the ability of a system, such as a solution, to resist changes in pH when acids or bases are added. Think of it like a sponge that absorbs extra water without overflowing. In biological systems, like our blood, buffering helps maintain a stable environment essential for proper function. It works by neutralizing excess acids or bases, ensuring that conditions remain steady. This is crucial for living organisms, as even small changes in acidity can disrupt processes and affect health. In essence, buffering capacity acts as a protective mechanism against fluctuations in chemical balance.
