Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent, then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water, sucrose, dialysis tubing, string, 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We tied off one end of the dialysis tubing to create a bag, filled it with distilled water, and tie of other end to close. The bag is carefully blotted to remove any water spilled during the filling and then weighed and recorded for an initial mass. Then we filled a 250 ml beaker with only distilled water. Immerse the bag in the beaker of distilled water and let stand for 30 minutes. After 30 minutes we removed the bag from beaker and carefully blot excess water to determi...

Diffusion And Osmosis Lab Report

Diffusion and Osmosis NGSSS: SC.912.L.14.2 Relate structure to function for the components of plant and animal cells. Explain the role of cell membranes as a highly selective barrier (passive and active transport). SC.912.L.14.3 Compare and contrast the general structures of plant and animal cells. Compare and contrast the general structures of prokaryotic and eukaryotic cells. AA Background: (Source: www.explorelearning.com) Diffusion is the process in which there is a net movement of molecules from a high area of concentration to a low area of c...

BIOLOGY OSMOSIS LAB REPORT 1. Research Question/ Aim How do the different sodium chloride concentrations of solutions affect the length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases, the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores, there will be net movement of water out of the potato cores. ...

SBI 3UO Ms. C. Evans Biology Lab Report Title: To determine the effect of surface area on the rate of osmosis. Abstract: The main aim of the experiment was to determine the effect on the rate of osmosis by the changing surface area. The changes were observed in the masses and surface area of the chopped potatoes which were initially of different surface area but same mass. The rate of osmosis increased with increase in surface area. And this increase in the rate of osmosis was directly proportional to th...
