The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. Thus‚ diffusion should not be confused with convection or advection‚ which are other transport mechanisms that use bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach starting

molecules of the food coloring equally distributed in the area of the water. Osmosis is a special type of diffusion where only the water molecules move. This happens through a selectively permeable membrane. It allows water and oxygen to move freely across the membrane. Osmosis only has an effect when the cell is in a hypotonic or hypertonic solution. A hypotonic solution is when the salt concentration

The Osmosis Lab SHS Lacrosse Monster #2 Dates performed: 10/10/11 and 10/11/11 Introduction: The purpose of the laboratory investigation was to observe the diffusion of water across a semi-permeable membrane. In this lab‚ dialysis tubing was used to represent the semi-permeable cell membrane. Three dialysis tubes were prepared with 5% sucrose solution and were soaked in solutions of different concentrations. The diffusion of water across a semi-permeable membrane is called osmosis. When
