to removed colored substances .Colored impurities can be removed by adding decolorizing carbon such as animal charcoal to the hot solution prior to filtration and the solution is kept hot for a brief period‚ shaken to wet and filtered. Adsorption occurs very rapidly and no advantage is gained by boiling the suspension for several minutes. It is a mistake to use more decolorizing charcoal than needed‚ for an excess may absorb some of the substance to be purified and causes losses. The solution was

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

NOISE CONTROL OF TWO STROKE PETROL ENGINE USING AQUA SILENCER SYNOPSIS Air pollution is most important from the public health point of view‚ because every individual person breathes approximately 22000 times a day‚ inhaling about 15 to 22 Kg of air daily. Polluted air causes physical ill effect decides undesirable aesthetic and physiological effects. Air pollution can be defined as addition to our atmosphere of any material‚ which will have a deterious effect on life upon our planet. The main pollutants contribute

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase
