Nikhil Gopalam October Mailbox #55 Affects of Osmosis and Diffusion Introduction: Perfume spreads in a room‚ hands bloat when left in water for too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute

Answers to Questions Activity 1: Simulating Dialysis (Simple Diffusion) (pp. 2–4) 9. All solutes except albumin are able to diffuse into the right beaker. Using distilled water in the right beaker and either the 100 MWCO or 200 MWCO membrane will remove urea from the left beaker and leave albumin If the left beaker contains NaCl‚ urea‚ and albumin‚ you can selectively remove urea by dispensing a concentration of NaCl into the right beaker equivalent to that in the left beaker and by using

As trade along the Silk Road grew‚ Chinese weavers wanted to design silks that would appeal to other cultures. (Cultural Diffusion & the Silk Route of Ancient China) Some examples of this are the silk rugs called “ The Tree of Life‚” that reflected upon the Persian culture. This rug contained the roundel animal symbol and scenes of saddled horsemen. They used thread wrapped
