Ion buffer
WebIn continuous buffer systems, the composition of the gel buffer and running buffer are essentially identical throughout the gel. They consist of a single separating gel and use the same buffer ions at the same pH throughout the sample, gel, and electrode reservoirs. Web30 dec. 2015 · The ion buffer capacity of heterogeneous (two-phase) systems has been studied relatively well only for the pH buffers (Pfendt 1995; Dougherty et al. 2006), partly because slow reactions make experimental studies difficult, partly because of the mathematical complexity of the theoretical calculations.

Het deeltje HZ kan een H+ ion af staan (reactie naar rechts) en het deeltje Z-kan een H+ ion opnemen (reactie naar links). HZ is dus een zuur en Z-is ... WebUses of Buffer Solutions. pH buffers or hydrogen ion buffers are some of the terms used to describe buffer solutions. To maintain an optimal pH for enzyme function, many organisms use buffer solutions. An application of the buffer used in pH regulation is the use of a bicarbonate or carbonic acid buffer system to monitor the pH of animal blood.
