WebOct 7, 2024 · What Is a Buffer? There are two key terms associated with buffers. A buffer is an aqueous solution that has a highly stable pH. A buffering agent is a weak acid or weak base that helps maintain the pH of an aqueous solution after adding another acid or base. If you add an acid or a base to a buffered solution, its pH will not change significantly. WebBuffers can react with both strong acids (top) and strong bases (side) to minimize large changes in pH. Buffers made from weak bases and salts of weak bases act similarly. For example, in a buffer containing NH 3 and NH 4 Cl, NH 3 molecules can react with any excess H + ions introduced by strong acids: ion group cfo

"WebMar 6, 2024 · By contrast, the acetate buffer’s pH after adding the same amount of HCl is 4.74. Thus, the pure water solution sees its pH fall from 7 to 2 (5 pH units), whereas the buffered solution saw its pH drop from 4.76 to 4.74 (0.02 pH units). Clearly, the buffer minimizes the impact of the added protons compared to the pure water. Buffer capacity " - How do buffers minimize ph changes
