In this experiment I am going to investigate how unlike assimilations of sucrose solution can alter the process of osmosis on a white potato chip, and in what way it does this.OsmosisAimIn this experiment I am going to investigate how differentconcentrations of sucrose solution can alter the process of osmosis ona potato chip, and in what way it does this.PredictionI predict that due to osmosis and diffusion when in that location is a pure watersolution the potato chip will swell as it absorbs the water toequalise.However, if there is a mild/rich sucrose solution on the let on side ofthe potato chip it will shrink as water is sucked out of them by theprocess of osmosis.ResearchIf substance has a semi-permeable wall with holes littler enough toallow small water molecules to pass through but non big enough toallow greater sized molecules such as sucrose molecules.Osmosis is a type of diffusion when there is a higher concentrationof a certain type of molecule on one side of a sem i-permeablemembrane, a process of diffusion (osmosis) tries to level out thebalance of the extremely concentrated solution to lower the concentrationuntil it is equal on both sides.For exampleSome water is placed in a science beaker (A), and thusly some 20% sucrose 80% water solution is placed in a piece of visking tubing (D).When this is placed in the water contained in the beaker (A) therebecomes an imbalance of concentrations either side of thesemi-permeable membrane, on the inside of the membrane there is astronger concentration or ratio of sucrose against water than there isin the outside.Therefore the sucrose would be required to equalise, by 10% or somoving to the outside of the tubing, there comes the problem.Due to the size of the small holes in the visking tubing, bigmolecules, such as dulcorate, C6H12O6 that is 24 atoms big, cannot passthrough, however small ones such as water, H2O with three atoms to amolecule, can.Therefore, since there is no way of moving the sugar, the best thingto do is to add more water to the inside of the visking tubing. Byosmosis and diffusion, the smaller molecules move into the viskingtubing whilst the bigger sugar molecules stay.That is osmosis. Plants also use this method to provide nutrients andvarious chemicals to their cells.EquipmentFor my experiment I will need a total ofFour test tubes one potato 2%, 5%, 10%, 20% sucrose and watersolution one knife one marble cutting plate aluminium blow foursticky labels.Method1. Cut the potato into equal strips and weigh them.
