# Rate of diffusion of potassium permanganate potassium dichromate and methylene blue1

Temperature has no effect on the permeability and diffusion rate of a substance potassium permanganate (kmno4), methylene blue solution, graph paper, petri dish . The effect of molecular weight on the rate of diffusion of potassium permanganate (kmno4), potassium dichromate (k2cr2o7) and methylene blue ¹ abstract the effect of molecular weight on the rate of diffusion was determined using the agar-water gel test. One drop of potassium permanganate (kmno4), potassium dichromate (k2cr2o7) and methylene blue were used each substance has a respective molecular weight of 158 g/mol, 294g/mol and 374 g/mol each substance has a respective molecular weight of 158 g/mol, 294g/mol and 374 g/mol.

Diffusion of methylene blue and potassium permanganate through the agar gel based on the diffusion rate changed as diffusion occurs in a gaseous, aqueous, and solid. On the experiment, potassium dichromate, potassium permanganate, and methylene blue in agar-water gel inside the petri dish were used to determine the partial rate and the average rate of diffusion after 30 minutes of observing, the diameter of the potassium permanganate has the biggest among the rest which is 14, compared to the potassium . Diffusion lab report 123,005 views amount of potassium permanganate adding different amount of potassium permanganate to the water can affect the rate of . Osmosis and diffusion make a prediction about the rates of diffusion of methylene blue and potassium permanganate through the agar gel diffusion rate (mm/min .

It can be depicted in table 43 that there is a relationship between the average rate of diffusion and molecular weight of potassium permanganate, potassium dichromate, and methylene blue kmno4 which has the lowest molecular weight attained the highest average rate of diffusion with 052 mm/min k2cr2o7, on the other hand, had 037 mm/min . 1 the effect of molecular weight and time on the rate of diffusion we will write a custom essay sample on any topic specifically for you for only $1390/page order now of potassium permanganate, potassium bichromate, and methylene blue1 scientific paper submitted in partial fulfilment of the demands in general biology i laboratory under prof read more. The relationship of molecular weight and rate of diffusion was determined using three colored substances with different molecular weights, namely potassium permanganate, potassium dichromate and methylene blue.

Potassium permanganate (kmno4), methylene blue (c16h18n3scl) had a drop in each well methylene blue, having the heaviest weight, diffused slowly therefore, the heavier the molecular weight, the slower the rate of diffusion. Potassium permanganate is a strong oxidizing agent the standard industrial use of this compound is in water treatment for color removal, taste and odor control, and removal of iron and manganese potassium permanganate also inactivates certain viruses and bacterias. The effect molecular weight on the rate of diffusion of potassium permanganate (kmno4), potassium dichromate (k2cr2o7) and methylene blue anna carmela santoalla.

Fill two holes with potassium permanganate and two holes with methylene blue of diffusion (mm/h) potassium permanganate 158 the osmosis rate every 30’ and . Diffusion of potassium permanganate and methylene blue activity 1 - diffusion of potassium permanganate & methylene blue what effect does solute molecular weight have on diffusion rate . Best answer: according to this site, methylene blue has a higher molecular weight than potassium permanganate therefore smaller, lighter molecules diffuse faster than larger, heavier ones.

## Rate of diffusion of potassium permanganate potassium dichromate and methylene blue1

1 rate of diffusion you will examine the relationship between molecular weight and diffusion by measuring the distance that the crystals methylene blue(31986 g/mol), potassium permanganate(158g/mol) and potassium dichromate(2942 g/mol) are able to migrate through an agar medium in a given amount of time. Some crystals of potassium permanganate (mw=158) on the left and methylene blue (mw=320) on the right time-lapse video w/ images taken every 30 seconds, but i don't remember how long this was in . Potassium permanganate rt methylene blue rt time (min) total diameter (mm) distance of diffusion (mm) rate (mm/min) total diameter .

- Drops of potassium permanganate (kmno4), potassium dichromate (k2cr2o7) and methylene blue(c16h18n3scl) were simultaneously introduced to each well methylene blue, having the largest molecular weight, displayed the smallest diameter (11 mm) and diffused at the slowest rate (020 mm/min).
- In lab, you observed the rate of diffusion of potassium permanganate and methylene blue through agar which dye migrated at a slower rate and why.

Compute the rate of diffusion of the potassium permanganate molecules in millimeters per minute as well as the rate of methylene blue prepare the lab report together with your introductions, hypothesis, discussions, results, conclussions, and then the references. Discussion 1 given the molecular weights of methylene blue, ferric chloride, and potassium permanganate, what can we conclude from the relationship of molecular weight to the rate of diffusion. Methylene blue has a higher molecular weight than the compound potassium permanganate potassium permanganate has smaller, lighter molecules which diffuse faster than methylene blue's larger .
