Labrador, 1st sem., 2012-2013 plume The effect of the molecular weighting on the esteem of dissemination using ii tests: the drinking glass tube and the agar- water supply mousse test. In the glass tube test, two like balls were soaked in two ends of the glass tube. ammonium hyd arranged oxide (NH3), with the lighter molecular weight value diffused at a faster rate. Thus, resulting in the formation of a bloodless smoke in the glass tube moving nigh to the side of the heavier substance Hydrochloric Acid (HCl). The agar-water change set-up consisted of a agar-water gel in a petri dish containing three tumesces. The compounds: green Permanganate (KmnO4), atomic number 19 Dichromate (K2Cr2O7) and 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 distribution.

INTRODUCTION There are several factors that affect the diffusion rate: Concentration Gradient the difference in assimilation between two areas. The greater the gradient, the faster the diffusion. Size and put to work 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 diff usion is faster in gases than in liquids (mo! re discharge 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 arse create currents (promotes mixing) Thus, it can be hypothesized that the substance with the lightest molecular weight (Hydrochloric Acid and grand Permanganate) will diffuse faster than of those the heavy ones. Since the compounds Hydrochloric Acid (HCl,...If you expect to get a full essay, order it on our website: BestEssayCheap.com
