BUFFERING FUNCTION: A GENERAL APPROACH FOR BUFFER BEHAVIOR …

WebWhen the bottle is open, the electrolyte is exposed to air. Air contains 0.04% CO2 and this gas is absorbed by the buffer solution as Carbonic acid which causes the pH of the solution to drop. Therefore the pH 4.01 buffer and pH 6.86 buffer are not as sensitive and the buffer quality does not degrade as strongly when the bottle is opened. WebThe pH of a phosphate buffer is usually maintained at a physiological pH of 7.4. How does a buffer work? Buffer, as we have defined, is a mixture of a conjugate acid-base pair that can resist changes in pH when small volumes of strong acids or bases are added.
