Acetic Acid/Sodium Acetate Buffer

An Acetic Acid/Sodium Acetate buffer is a solution that helps maintain a steady pH level, typically around 4.75. It is made by mixing acetic acid (a weak acid) with sodium acetate (its salt). When acids or bases are added, the buffer reacts to minimize pH changes—acetic acid neutralizes added bases, while sodium acetate neutralizes added acids. This stability makes it useful in biological, chemical, and industrial applications where maintaining a specific pH is crucial for processes and reactions to occur correctly.
