Diffusion of potassium permanganate crytstals crystals spread through water quickly (roughly 3 mins), crystals spread through agar gel much slower diffusion of sodium hydroxide through agar. Potassium permanganate is an inorganic chemical compound and medication as a medication it is used for cleaning wounds and dermatitis it has the chemical formula kmno 4 and is a salt consisting of k + and mno . The effect of molecular weight on the rate of diffusion of substances1 angel mae o ombid group 3 sec u-1l october 19, 2014 1 a scientific paper submitted in partial fulfillment of the requirements in general biology i laboratory under prof blesshe querijero, 1st sem, 2014-2015 abstract the. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate, agar plate set-up was used to observe the diffusion of different substances the methylene blue and potassium permanganate (kmno4) was used and placed in the plate.
Experiments: osmosis and diffusion diffusion experiment (potassium permanganate) to it 4 observe what happens to the crystals also observe the change in the. The rate of diffusion of potassium permanganate & methylene blue through agar is different why potassium = smaller & lighter methylene blue = heavier & larger.
Kmno4 first dissolved in the water a concentration gradient now existed between the kmno4 crystals and the surrounding water (1) net diffusion now occurred down this gradient (2) until a diffusion equilibrium was established (3. Diffusion between potassium permanganate and distilled water: experiment i did an experiment which was putting a sprinkle of kmno4 into a petri dish of distilled water the idea was to place the sprinkle in the middle of the dish and measure how far the kmno4 moves out during a 20 second time span. The study aims to determine how the molecular weight affects the rate of diffusion of potassium permanganate (kmno4), potassium dichromate (k2cr2o7), and methylene blue with respect to time the experiment was conducted at room c-107, institute of biological sciences, university of the philippines-los banos college, laguna, august 4, 2011.
Potassium permanganate (kmno4), a powerful oxidizing agent, is readily available without prescription tissue contact produces coagulation necrosis & the lethal consequences of oral ingestion are well described, with most deaths because of airway edema & obstruction or circulatory collapse. Diffusion of potassium permanganate ( kmno4 ) diffusion is the motion of molecules from an country of high concentration to an country of low concentration across a permeable membrane as a consequence of kinetic energy of random gesture. Analyzing a diffusion laboratory investigation in summarizing the data, the class arranged the beakers according to the time it took for the potassium permanganate to completely diffuse.
Published: tue, 25 apr 2017 1 the effect of molecular weight and time on the rate of diffusion of potassium permanganate, potassium dichromate, and methylene blue1 scientific paper submitted in partial fulfillment of the requirements in general. The potassium permanganate (kmno4), which has the smallest molecular weight have the fastest average rate of diffusion compared to the other two substances with higher molecular weight thus, molecular weight affects the diffusion. 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.
Dropping crystals of potassium permanganate into a tall column of water leads to the slow dissolution and diffusion of the potassium permanganate throughout the column over a semester's time. Beaker distilled water kmno4 before after kmno4 diagram showing diffusion before and after observation: when the kmno4 was added to the water all the crystals gradually dropped to the bottom of the beaker the colour at the bottom of the beaker was dark purple. Diffusion of potassium permanganate (kmno4) diffusion is the movement of molecules from an area of high concentration to an area of low concentration across a permeable membrane as a result of kinetic energy of random motion. Aim:to discover what factors affect the rate of diffusion of potassium permanganate crystals in water statement:what will happen how will room temperate solutions or heated solutions increase the rate of diffusion of the potassium crystalshypothesis:heat will speed up the process of diffusion because heat will give out energy that will be able to speed up the process of spreading the.
