Why does methylene blue diffuse more quickly through 5% agar?
Why does methylene blue diffuse more quickly through 5% agar?
a. Methylene blue had a higher molecular weight, so it was able to diffuse more rapidly spreading farther through the agar in the same time.
What diffuses faster potassium permanganate or 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 diffused through the agar at a faster rate?
This was achieved by obtaining agar in a petri dish with two wells to hold the liquid compounds. The rate was measured by time and diameter distance diffused. This process was observed for 60 minutes at 15 minute intervals. Potassium permanganate diffused at a much faster rate than methylene blue.
Why were the diffusion rates between methylene blue and food coloring different?
Diffusion is inversely proportional to molecular weight. The lesser is the molecular weight, the faster the molecules diffuse. The Red dye difuses faster that the blue dye since the blue dye has a higher molecular weight.
In which experiment was diffusion the fastest?
liquid experiment
-In which experiment was diffusion the fastest? Diffusion was faster in the liquid experiment. – What accounts for the difference in speed? The cells in the substance made to diffuse are much bigger which means that the dye cant travel as it would normally do to dissolve in water.
Which molecule would have a faster diffusion rate?
Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.
Why do smaller molecules diffuse faster?
Temperature: Particles move due to the kinetic energy associated with them. As temperature increases, the kinetic energy associated with each particle also increases. Smaller particles on the other hand will diffuse faster because they can move faster.
Does potassium permanganate diffuse more rapidly through water or through agar gel?
Does potassium permanganate diffuse more rapidly through water or through agar gel? Why? It diffuses more rapidly through water, because there are no particles to slow the movement of dye. The pore size of the dialysis sac used in our experiment determines which molecules can pass.
Which molecules diffuse at the fastest rate?
At any given temperature, small, light molecules (such as H2, hydrogen gas) diffuse faster than larger, more massive molecules (such as N2, nitrogen gas) because they are traveling faster, on the average (see heat; kinetic-molecular theory of gases).
What is the molecular weight of methylene blue?
319.85 g/mol
Methylene blue/Molar mass
Methylene blue dye (MBD) (CI No. 52015) is a heterocyclic aromatic chemical compound with the molecular formula of C16H18N3SCl and molecular weight of 319.85 g/mol.
How does the dye relate to diffusion?
The food coloring mixes through the hot water faster than it mixes with the cold water. This makes it easier for the dye to get mixed throughout the hot water. Because diffusion happens from high concentration to low concentration, the more molecules are moving, the more opportunities they have to mix together.
Why is potassium permanganate used in diffusion?
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.
Why does methylene blue diffuse faster than potassium permanganate?
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. The molecular weight and time affect the diffusion of the particle. Additionally, does potassium permanganate diffuse more rapidly through water or through agar gel why?
Why does dye diffuse more rapidly in agar than in water?
(A) It diffuses more rapidly through agar, because water attracts the dye molecules and slows their movement. (D) It diffuses more rapidly through agar, because there are channels in it that help the dye solution to move.
Why is methylene blue used as a dye?
Lastly, methylene blue is used as dye to identify bacteria and nucleic acids. The dye will have the deepest shade of blue when in contact with acids. As indicators and oxidizing agents, the substances stated above must prove that their diffusion must be fast in order to do their functions.
Which is the least molecular weight potassium or methylene blue?
Results showed that potassium permanganate (MW 158 g/mole) which has the least molecular weight had the highest average rate of diffusion compared to methylene blue (MW 374 g/mole), which has the greatest molecular weight among the three.
