WebMar 9, 2024 · Buffers in chemistry are made up of either a weak acid and its conjugate base, or a weak base and its conjugate acid. Buffers are in dynamic equilibrium. This means the reactions go in opposite directions, as shown in the chemical equations below. Dissociation constant – the ideal pKa (acidic strength) range is between 6 and 8.
