Which method cannot be used for the coagulation of the lyophobic sol?a...
Electroosmotic flow (or electro-osmotic flow, often abbreviated EOF; synonymous with electroosmosis or electroendosmosis) is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane, microchannel, or any other fluid conduit. Because electroosmotic velocities are independent of conduit size, as long as the electrical double layer is much smaller than the characteristic length scale of the channel, electroosmotic flow will have little effect. Electroosmotic flow is most significant when in small channels. Electroosmotic flow is an essential component in chemical separation techniques, notably capillary electrophoresis. Electroosmotic flow can occur in natural unfiltered water, as well as buffered solutions.

Which method cannot be used for the coagulation of the lyophobic sol?a...
Electroosmosis
Electroosmosis is a phenomenon where a solvent or liquid moves in an electric field. It is not a method that can be used for the coagulation of lyophobic sols. Here's why:
Reasons why Electroosmosis cannot be used for coagulation of lyophobic sols:
- Definition: Electroosmosis involves the movement of a solvent under the influence of an electric field. It is not directly related to the coagulation of lyophobic sols.
- Mechanism: The process of coagulation of lyophobic sols typically involves destabilizing the particles in the sol so they come together to form aggregates. Electroosmosis does not directly contribute to this aggregation process.
- Effect on sol particles: Electroosmosis may not have a significant impact on the particles in a lyophobic sol in terms of causing them to coagulate. Other methods such as persistent dialysis, boiling, or electrophoresis are more effective in inducing coagulation.
- Application: Electroosmosis is more commonly used in fields like electrochemistry and separation techniques rather than in the coagulation of colloidal particles.
In conclusion, while electroosmosis is a fascinating phenomenon with various applications, it is not a suitable method for the coagulation of lyophobic sols. Other techniques like persistent dialysis, boiling, or electrophoresis are more appropriate for inducing coagulation in lyophobic sols.

Coagulation is the destabilization of Colloids by neutralizing the electric charge of the dispersed phase particles, which results in aggregation of the colloidal particles.
