A Scientific Paper on Diffusion

A Paper on Compound Diffusion 1 Karl Joseph D. Hintay sepa tempo 3 Sec.

Labrador, 1st sem., 2012-2013 creep The effect of the molecular weighting on the esteem of dispersal using ii tests: the drinking glass tube and the agar- water supply mousse test. In the glass tube test, two cotton wool balls were soaked in two ends of the glass tube. ammonium hyd prescribed oxide (NH3), with the lighter molecular weight value diffused at a faster rate. Thus, resulting in the formation of a dead smoke in the glass tube moving nearby to the side of the heavier substance Hydrochloric Acid (HCl). The agar-water gelatin set-up consisted of a agar-water gel in a petri dish containing three tumesces. The compounds: green Permanganate (KmnO4), thousand Dichromate (K2Cr2O7) and Met hylene 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 dissemination.

INTRODUCTION There are several factors that affect the airing rate: Concentration Gradient the difference in compactness between two areas. The greater the gradient, the faster the diffusion. Size and effect of the Molecules small molecules that fit through willing pass at a faster rate. Temperature the warmer, the faster it leases (more kinetic energy in the particles) type of strong point diffusion is fa ster in gases than in liquids (more dischar! ge space between the molecules of a gas as well as greater kinetic energy) Movement of the medium water or air currents speed up diffusion e.g. brainchild or heating move create currents (promotes mixing) Thus, it can be hypothesized that the substance with the lightest molecular weight (Hydrochloric Acid and super acid Permanganate) will diffuse faster than of those the heavy ones. Since the compounds Hydrochloric Acid (HCl,...If you want to get a full essay, order it on our website: BestEssayCheap.com
