1 Ιαν 2009 · The chapter discusses buffers, its principles, selection, preparation, and practice. It has become important to find buffers to stabilize hydrogen ion concentrations while not interfering with the function of the enzyme being studied.
1 Ιαν 1972 · Such substances are known as hydrogen ion buffers since they tend to prevent pH changes. In their presence, the addition or removal of hydrogen ion simply shifts con- centrations to restore equilibrium, increasing or decreasing by a small amount the relatively large reservoir of protonated buffer.
A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...
15 Μαΐ 1980 · Five new zwitterionic hydrogen ion buffers are described for the first time. These buffers, all N-substituted 3-amino-2-hydroxypropanesulfonic acids, with pK a 's between 6.9 and 7.9 have been subjected to a number of stringent tests in mammalian tissue culture, plant pathology, and virology to detect inhibitory effects. They appear to be ...
1 Αυγ 2006 · Before we begin a discussion of buffers and how they control hydrogen ion concentrations, a brief explanation of the role of water and equilibrium constants of weak acids and bases is...
3 Μαΐ 2021 · They laid out the properties required for useful, biochemically relevant hydrogen-ion buffers and then synthesized and tested 10 of them. Soon after, these buffers became commercially available. Since then, most of us never gave them a second thought.
