Does Potassium Permanganate Diffuse More Rapidly Through Water or Through

question 12

Multiple Choice

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

• A) It diffuses more rapidly through water, because there are no particles to slow the movement of dye.
• B) It diffuses more rapidly through agar, because there are channels in agar that help the dye solution to move.
• C) It diffuses more rapidly through water, because there are more particles for the dye to bounce off of.
• D) It diffuses more rapidly through agar, because water attracts the dye molecules and slows their movement.
