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 do you think diffused faster through the agar and why?
Potassium permanganate
has a lower molecular weight so it’s rate of diffusion is greater than Methylene blue. d. Potassium permanganate had a lower molecular weight, so it was able to diffuse more rapidly spreading farther through the agar in the same time.
Which solution diffuse the fastest?
Carbon dioxide
is inherently more soluble than oxygen, and thus diffuses much faster than oxygen into liquid.
Does red or blue dye diffuse faster in corn syrup?
while then blue dye’s is 793 g/mole. 2. Which dye diffused the fastest? …
red dye
has a lower molecular weight, it diffused faster in the corn syrup.
Why did methylene blue diffuse faster than potassium permanganate?
Dye molecules for methylene blue move faster than the potassium permanganate
because the molecular weight of methylene blue is more than that of potassium permanganate
. In diffusion, lighter molecules diffuse faster as compared to heavier molecules.
What substances can move into or out of cells by diffusion?
Water, carbon dioxide, and oxygen
are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
When oxygen is more concentrated outside of a cell?
What happens if the concentration of oxygen molecules outside the cell is lower than that inside the cell?
Diffusion
…..the oxygen molecules will move inside the cell until the concentration is equal inside and outside.
Which gas diffuses faster hydrogen or oxygen?
Hydrogen (H2) gas diffuses 4 times faster than
oxygen (O2) gas. Explanation: According to Graham’s law of diffusion, the rate of diffusion or movement of gas is inversely proportional to the square root of it’s molecular weight. Among H2 , O2 , CO, and N2 , the gas with least mass is hydrogen.
Why does potassium permanganate diffuse faster in hot water?
The
kinetic energy of particles of water increases with increase in temperature
. Therefore , the particles of hot water move faster. … hence potassium per magnet diffuses faster in hot water than cold water .
Which gas has slowest rate of diffusion?
Neon is the fastest.
Chlorine
is the slowest.
Which of the two dyes diffused faster?
Which dye diffuses at a faster rate:
Red
or Blue dye? 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.
Is red or blue dye heavier?
Overall,
blue is heavier than red
, red is heavier than green, and green is heavier than yellow. Brighter colors weigh less than darker ones. Increasing saturation makes colors appear to weigh less. Brighter backgrounds make dark colors look lighter (less heavy) and bright colors look heavier.
Which dye has the fastest rate of diffusion regardless of temperature?
Question: Questions 1. Describe the effect of temperature on rate of diffusion 2. Which dye had the fastest rate of diffusion, regardless of temperature?
33333555555JSSUUUUUUUUU
3.
What particle diffused the farthest 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.
What happens when potassium permanganate is added to water?
Potassium permanganate is available as a dry, purplish solid. A device injects a solution of potassium permanganate into the water between the water pump and holding tank. Potassium
permanganate oxidizes iron, manganese, and hydrogen sulfide into particles
. … The water should be colorless when it leaves the filter.
How can you explain diffusion using potassium permanganate?
Potassium Permanganate Diffusion in Water
Place the crystals at the bottom of the beaker.
Steadily add distilled water to
the beaker up to 35 milliliters or so of volume. Because of the random movement of potassium permanganate particles, a dense purple solution forms in water at base of the beaker.
