Lab Report Title: – Osmosis Visking tube lab Research Question: Does increasing the level of sucrose increase the procedure of osmosis? Introduction: This experiment is called the osmosis visking tube. This experiment is to investigate the relationship between solute concentration and the movement of water through semipermeable membrane by the process of osmosis. The purpose of this The Visking tubing apparatus establishes the osmosis procedure. The Visking tubing is a semipermeable membrane filled up with concentrated sucrose solution. The surface of the semipermeable membrane symbolizes the visking tubes and the mixture demonstrates the cytoplasm. If the Visking tube is absorbed in water, after a period of time, it will be have water inside water, this is because the water molecules can pass through the tubing, while the larger sugar molecules cannot diffuse out from the tubing because the size of sugar molecules do not allow it to go through the tubing. Therefore, this experimentation indicated that the sucrose molecules cannot diffuse from the concentration of the dilute solution, while on the other hand the water molecules diffuse from the dilute solution to the concentrated one. Hypothesis: If the (independent variable) sucrose of the dilute solution is …show more content…

It justifies the idea that increasing the concentration of sucrose does in fact speed up the rate of osmosis, an therefore increase the mass of the Visking tube. This happens due to the water molecules moving from a high water concentration to a low water concentration. Another reason why this hypothesis is correct is because sucrose particles are too large to go through the membrane therefore the sucrose does not diffuse into the water. According to the mean graph there is a clear outline that indicates constant acceleration, which justifies that the increase of the independent variable affects the dependent
