Does potassium permanganate diffuse more rapidly through water or through agar gel? Why?

Question

Quizplus · Accepted Answer

Potassium permanganate diffuses more rapidly through water because water is a less dense medium compared to agar gel, which means there are fewer obstacles to impede the movement of the dye molecules. Agar gel is a semi-solid medium that contains a network of fibers creating a more structured environment, which slows down the diffusion process compared to the relatively free-moving environment in water.
