WebSep 29, 2024 · A base is a substance that reacts with an acid in an acid-base reaction. The mechanism through which a base works has been argued throughout history. Generally, a base either accepts a proton, … WebBuffer solutions maintain a stable pH by neutralizing added acids or bases. They consist of a weak acid and its conjugate base, which exchange protons and hydroxide ions to form water. The Henderson-Hasselbalch equation expresses the pH as a function of the PKa and the ratio of the base and acid concentrations. Sort by: Top Voted Questions
