Throughout this lab‚ diffusion and osmosis has been seen and tested through experiment. In part A of the lab‚ diffusion was demonstrated with two solids and an agar gel petri dish. One crystal of potassium permanganate and one crystal of methylene blue were placed on either side of an agar gel petri dish. The purpose of this experiment was to determine which of the crystals would diffuse across the gel more. So the question is‚ which solid would have a higher rate of diffusion through the agar‚ methylene

DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

Its adaptation to a parallel synthesis format is straightforward. Since the dyes vary widely in color‚ the diversity of this parallel synthesis becomes obvious. It includes techniques on diazotization and electrophilic substitiution. The experient belo is made to allow studens to

HEALTH HAZARDS OF THE DYE INDUSTRY . The first step in prevention of poisoning in the dye industry includes well-ventilated‚ properly equipped buildings. Selection of workmen is important and the use of the best methods in manufacturing. These investigations‚ which are based on 2‚500 employees‚ whose blood was tested periodically‚ yield some minor diagnostic material. The hazards of the dye industry are those connected with any industry plus the poisonous chemicals necessarily handled in the

Tie dye is haute Sixties is back and we don’t mean bell-bottom pants‚ vests or long hair. We mean tie dye‚ the most sought after patterns this summer. One can hardly imagine the chaotic swirls to be considered high fashion. The mere mention brings memories from the past‚ the wild psychedelic prints and the hippy culture. Yet the colorful patterns are making a comeback with who is who of the fashion industry spotted in one. The demographic might have changed the overall style has changed what hasn’t
