Labrador, 1st sem., 2012-2013 airlift The effect of the molecular weighting on the esteem of dispersion using ii tests: the drinking glass tube and the agar- piss mousse test. In the glass tube test, two cotton plant balls were soaked in two ends of the glass tube. ammonium hyd treasured oxide (NH3), with the lighter molecular weight value diffused at a faster rate. Thus, resulting in the formation of a exsanguinous smoke in the glass tube moving closer 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), chiliad Dichromate (K2Cr2O7) and Meth ylene 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 spreading.

INTRODUCTION There are several factors that affect the dissemination rate: Concentration Gradient the difference in niggardliness between two areas. The greater the gradient, the faster the diffusion. Size and constellation 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 mediocre diffusion is faster in gases tha n in liquids (more 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 shadower create currents (promotes mixing) Thus, it can be hypothesized that the substance with the lightest molecular weight (Hydrochloric Acid and honey oil Permanganate) will diffuse faster than of those the heavy ones. Since the compounds Hydrochloric Acid (HCl,...If you wishing to get a full essay, order it on our website: BestEssayCheap.com
