In starch solution, if the dispersed phase and the dispersion medium are separated by evaporation, the colloidal solution can be regained by remixing the dispersed phase and dispersion medium. Hence these are called reversible solutions are highly stable because of the high interaction between the dispersed phase and medium.

In which of the following, the dispersed phase and medium can be separ...
Starch Solution:
Starch solution consists of starch particles dispersed in water, where starch particles act as the dispersed phase and water acts as the medium.
Evaporation for Separation:
When a starch solution is subjected to evaporation, the water component of the solution evaporates due to the application of heat. As water has a lower boiling point compared to starch particles, it evaporates first leaving behind the solid starch particles. This process helps in the separation of the dispersed phase (starch particles) and the medium (water).
Process of Evaporation:
- The starch solution is heated in a container.
- The water component of the solution evaporates, turning into steam.
- The steam is collected or allowed to escape, depending on the setup.
- The remaining solid starch particles are left behind in the container.
Separation of Dispersed Phase and Medium:
Through the process of evaporation, the dispersed phase (starch particles) and the medium (water) in the starch solution can be effectively separated. The solid starch particles remain in the container while the water component is removed as steam. This separation method is based on the differences in the physical properties of the dispersed phase and the medium, specifically their boiling points.
Therefore, in the case of a starch solution, the dispersed phase and medium can be separated by evaporation, making option 'D' the correct answer to the question.
