The rate of solid-liquid extraction is limited by the_________________?
Correct answer: E. All A , B. & C.
- A. Phase change of the solute as it dissolves in the solvent
- B. Diffusion of the solute through the solvent in the pores to the outside of the particle
- C. Diffusion of the solute from the solution in contact with the particle to the main bulk of the
- D. solution
- E. All A , B. & C.
Explanation
Solid-liquid extraction can involve solute dissolution, diffusion through the particle pores, and external diffusion from the particle surface into the bulk liquid. The overall rate may therefore be limited by any or all of these resistances.
