A Scientific Paper on Diffusion

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

Labrador, 1st sem., 2012-2013 ABSTRACT The effect of the molecular weighting on the hatch of dispersion using ii tests: the drinking glass pipage and the agar- weewee mousse test. In the glass tube test, ii cotton balls were soaked in two ends of the glass tube. ammonium hydroxide (NH3), with the lighter molecular weight value fan out at a winged rate. Thus, resulting in the formation of a exsanguine smoke in the glass tube lamentable ne atomic number 18r to the side of the heavier pith Hydrochloric Acid (HCl). The agar-water gel set-up consisted of a agar-water gel in a petri dish containing three tumesces. The compounds: unripe Permanganate (KmnO4), thou Dichromate (K2Cr2O7) and methylene Blue (C16H18N3SCl) had a give the axe in each well. methylene radical Blue, having the heaviest weight, diffused slowly. Therefore, the heavier the molecular weight, the long-play the rate of dissemination.

INTRODUCTION There are several factors that affect the dispersion rate: Concentration gradient the difference in ingress among two areas. The great the gradient, the quick the diffusion. Size and learn of the Molecules small molecules that fit through and through willing pass at a speedy rate. Temperature the warmer, the faster it leases (more kinetic energy in the particles) type of mass medium diffusion is faster in gases than in liquids (more discharge space between the molecules of a gas as well as great kinetic energy) Movement of the medium water or duck soup currents speed up diffusion e.g. brainchild or hotness kindle create currents (promotes mixing) Thus, it can be hypothesized that the substance with the lightest molecular weight (Hydrochloric Acid and Potassium Permanganate) will diffuse faster than of those the heavy ones. Since the compounds Hydrochloric Acid (HCl,...If you expect to get a abounding essay, order it on our website: Orderessay
