How does a buffer reduce severe changes to ph

WebJan 30, 2024 · A buffer is able to resist pH change because the two components (conjugate acid and conjugate base) are both present in appreciable amounts at equilibrium and are able to neutralize small amounts of other acids and bases (in the form of H 3 O + and OH -) when the are added to the solution. WebApr 12, 2024 · The substrates were prepared by sonication in assay buffer (100 mM potassium phosphate buffer, 50 mM KCl; pH 7.4) supplemented with 5 mM CHAPS and FA-free BSA (Sigma- Aldrich) was added to get a final concentration of 1%. The assays were stopped at 75°C for 10 min and FA release was measured.
