Zeta potential is [|electric potential]  in the interfacial [|double layer]  (DL) at the location of the [|slipping plane]  versus a point in the bulk fluid away from the interface. In other words, zeta potential is the potential difference between the [|dispersion medium]  and the stationary layer of fluid attached to the [|dispersed particle] . A value of 25 mV (positive or negative) can be taken as the arbitrary value that separates low-charged surfaces from highly-charged surfaces. The significance of zeta potential is that its value can be related to the stability of colloidal dispersions (e.g., a multivitamin syrup). The zeta potential indicates the degree of repulsion between adjacent, similarly charged particles (the vitamins) in a dispersion. For molecules and particles that are small enough, a high zeta potential will confer stability, i.e., the solution or dispersion will resist aggregation. When the potential is low, attraction exceeds repulsion and the dispersion will break and flocculate. So, colloids with high zeta potential (negative or positive) are electrically stabilized while colloids with low zeta potentials tend to [|coagulate]  or [|flocculate] <span style="color: black; font-family: "Times New Roman","serif"; font-size: 12pt;"> as outlined in the table. Zeta potential is widely used for quantification of the magnitude of the electrical charge at the double layer. However, zeta potential is not equal to the [|Stern potential] or [|electric surface potential] in the double layer. Such assumptions of equality should be applied with caution. Nevertheless, zeta potential is often the only available path for characterization of double-layer properties. Zeta potential should not be confused with [|electrode potential] or [|electrochemical potential] ( because electrochemical reactions are generally not involved in the development of zeta potential).
