Concentrations of sucrose solution, cause a Potato chip of any given size or weight to Become larger or smaller. Notes on Osmosis Osmosis process was first discovered in 1748 by a French Scientist whom observed water diffuse spontaneously through a pig bladder. In nature, when there is a membrane as a separation medium, water will generally transfer from the least contaminant concentration side to the higher contamination side. The flow will stop when osmotic pressure on both sides is equalized. Reverse Osmosis, as its name implies, apply pressure on the higher concentrated contaminant side to force the clean water into the lower concentration side, thus generation of more cleaner water. Osmosis is an important physical process that occurs in and around all living cells. It can be defined as the diffusion of water molecules through a semi-permeable membrane from a weak to a strong solution. Many cell membranes behave as semi permeable...
