Test Tube Aluminum Foil
2,055 wordsOsmosis Lab Purpose The purpose of this lab is to determine the concentration of solutes inside of a potato s cell. We also want to know the composition of potato water and stuff. Also the scientific Phenomenon studied of diffusion/ Osmosis. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis is process by which water molecules diffuse across a cell membrane from an area of higher concentration to an area of lower concentration. ...

Sodium Chloride Permeable Membrane
2,568 wordsScenario Plants in the soil have their roots in a dilute solution of mineral ions. When they are suddenly flooded with seawater, concentration of which is 0. 3 molar Sodium Chloride, they are observed to wilt and become flaccid. Aim The aim of this experiment is to investigate the movement of water into and out of plant cells by osmosis. The cells chosen for study will be taken from potato tubers as they provide a ready supply of uniform material. Background Information Any substance dissolved i...
