Labrador, 1st sem., 2012-2013 lineation The effect of the molecular weighting on the esteem of dispersion using ii tests: the drinking glass tube and the agar- water supply mousse test. In the glass tube test, two cotton balls were soaked in two ends of the glass tube. ammonium hyd ordaind 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 near to the side of the heavier substance Hydrochloric Acid (HCl). The agar-water colloidal gel set-up consisted of a agar-water gel in a petri dish containing three tumesces. The compounds: green Permanganate (KmnO4), jet Dichromate (K2Cr2O7) and Methyle ne 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 distribution.

INTRODUCTION There are several factors that affect the dispersal rate: Concentration Gradient the difference in slow-wittedness between two areas. The greater the gradient, the faster the diffusion. Size and variant 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 specialty diffusion is f aster in gases than in liquids (more discha! rge 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 bed create currents (promotes mixing) Thus, it can be hypothesized that the substance with the lightest molecular weight (Hydrochloric Acid and chiliad Permanganate) will diffuse faster than of those the heavy ones. Since the compounds Hydrochloric Acid (HCl,...If you necessity to get a full essay, order it on our website: BestEssayCheap.com
