The Effect of Molecular Weight to the Diffusion Rate of Substances[ 1 ] The consequence of molecular weight to the rate of diffusion of substances had been obtained through agarose-water gel experiment. Drops of the undermentioned dye samples were used as controlled variables: K permanganate, K bichromate and methylene blue. Each dye has a molecular …
Introduction: Perfume spreads in a room, hands bloat when left in water for too long (shrilling is a common misconception), a tea bags 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 …
Introduction The resting membrane potency ( RMP ) is an electrical potency difference in cells, happening across their plasma membranes. The cytol of the cell is electrically negative in comparing to the environing extracellular fluid, this difference in electrical charge gives rise to the RMP. The RMP is indispensable for the operation of many electrically …
AbstractionDiffusion is the procedure where molecules spread into infinites. It was observed that the formation of ammonium chloride was near the hydrochloric acid intending the ammonium hydroxide diffused faster. One factor that affects the rate of it is the molecular weight of a substance. if molecular weight affects the rate of diffusion, so, the higher …
Stacy Hernandez Period 1 Mrs. Riley AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell, it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion, it is as if a bottle of perfume is opened at …
Diffusion and Osmosis |[pic] | |Introduction: Atoms and molecules are constantly in motion. This kinetic energy causes the molecules to bump into each other and move in different directions. This motion is the fuel for diffusion. Diffusion is the random movement of molecules from an area of higher concentration to an area of lower concentration. …
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature, molecular weight, and movement. To test the rate of diffusion a drop of dark …
