Ampholyte concentrations of 0.5–2.0% are used for most applications. Under the influence of the applied electric field, carrier ampholytes have the capacity to generate a pH gradient along the length of the capillary. Without considering at this stage how the gradient is formed, let us examine the behavior of a zwitterionic solute toward the ...

2020年8月15日 · An ampholyte is a compound which reacts with both acids and bases. A clear solution of sodium hydroxide is added to a clear solution of zinc chloride. A white precipitate is formed: the insoluble ampholytic compound zinc oxide. Either acid or base will dissolve this precipitate by the following reactions: ZnO (s) + 2 HCl → ZnCl 2(l) + H 2 O. OR
