Labrador, 1st sem., 2012-2013 see The effect of the molecular weighting on the esteem of airing using ii tests: the drinking glass tube and the agar- body of water mousse test. In the glass tube test, two cotton plant balls were soaked in two ends of the glass tube. ammonium hyd wanderd oxide (NH3), with the lighter molecular weight value diffused at a faster rate. Thus, resulting in the formation of a exsanguine smoke in the glass tube moving warm 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), thousand Dichromate (K2Cr2O7) and Methy lene 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 public exposure.

INTRODUCTION There are several factors that affect the diffusion rate: Concentration Gradient the difference in ducking between two areas. The greater the gradient, the faster the diffusion. Size and manakin 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 metier diffusion is faster in gases than in liquids (more discharge space betwe! en 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 goat 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 emergency to get a full essay, order it on our website: OrderCustomPaper.com
