Question

does potassium permanganate diffuse more rapidly through water or through agar gel? why? it diffuses more rapidly through agar, because there are channels in agar that help the dye solution to move. it diffuses more rapidly through water, because there are no particles to slow the movement of dye. it diffuses more rapidly through agar, because water attracts the dye molecules and slows their movement. it diffuses more rapidly through water, because there are more particles for the dye to bounce off of.

Explanation:

Diffusion rate depends on medium obstruction. Water, a liquid with fewer structural obstacles, allows faster movement of potassium permanganate than agar gel (a semi-solid with a network structure that hinders diffusion).

Answer:

It diffuses more rapidly through water, because there are no particles to slow the movement of dye.
