Why did the potassium permanganate move faster than the methylene blue?

Why did the potassium permanganate move faster than the methylene blue?

Methylene blue it has a higher molecular weight than potassium permanganate, therefore the smaller, the lighter the molecules are diffused faster than the heavier one.

Why is potassium permanganate used in diffusion experiment?

Because of the random movement of potassium permanganate particles, a dense purple solution forms in water at base of the beaker. The purple solution will slowly spread into the rest of the water throughout the beaker creating a less dense but evenly colored purple solution.

What is the experiment on diffusion of dye through agar about?

The rate at which molecules diffuse can be determined by the relationship of molecular weight and that rate of diffusion through a membrane. Hypothesis of this experiment is that the fluid with higher molecular weight will diffuse at a slower rate and distance.

Why was potassium permanganate and methylene blue run twice in the experiment?

Methylene blue had a higher molecular weight, so it was able to diffuse more rapidly spreading farther through the agar in the same time. Potassium permanganate had a higher molecular weight, so it was able to diffuse more rapidly spreading farther through the agar in the same time.

Is potassium permanganate larger than methylene blue?

Potassium Permanganate is approximately half the molecular weight of Methylene Blue and diffuses more rapidly than Methylene Blue, resulting a slightly larger radius for the Potassium Permanganate dye spot than for Methylene Blue.

Which dye the methylene blue or the potassium permanganate diffuse at the fastest rate?

How will the distribution of molecules occur when diffusion is complete in a solution?

Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes “down the concentration gradient.” The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop.

Does methylene blue or potassium permanganate diffuse faster?
