In this look into I am spill to investigate how different concentrations of sucrose reply can alter the adjoin of osmosis on a potato chip, and in what way it does this.OsmosisAimIn this experiment I am going to investigate how differentconcentrations of sucrose root can alter the change of osmosis ona potato chip, and in what way it does this.PredictionI predict that due to osmosis and dissemination when there is a pure pissingsolution the potato chip will swell as it absorbs the body of pissing toequalise.However, if there is a mild/rich sucrose solution on the out 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 small enough toallow small water molecules to whelm through but not big enough toallow greater sized molecules such as sucrose molecules.Osmosis is a quality of diffusion when there is a higher concentrationof a certain type of molecule on one side of a semi-per meable membrane, a process of diffusion (osmosis) tries to level out thebalance of the highly concentrated solution to lower the concentrationuntil it is equal on both sides.For example around(a) water is placed in a science beaker (A), and then 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. referable to the size of the small holes in the visking tubing, bigmolecules, such as sugar, C6H12O6 that is 24 atoms big, cannot passthrough, however small ones such as water, H2O with triplet atoms to amolecule, can.Therefore, since there is no way of moving the sugar, the best amourto do is to add more water to the inside of the visking tubing. Byosmosis and diffusion, the small molecules move into the viskingtubing whilst the bigger sugar molecules stay.That is osmosis. Plants also use this regularity 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 prod one marble cutting plate aluminium foil foursticky labels.Method1. Cut the potato into equal strips and weigh them.
