Dharam Taylor 11AP                Mr Shorter  To Investigate The Affect Of Concentration Of Salt Solution On The Mass Of Potato Chips Aim:The aim of this investigation is to see whether the amount of salt solution affects the mass of the potato chip Hypothesis:In the solution below, water will diffuse from the dilute solution into the concentrated solution through the process of osmosis.  Therefore the dilute solution level will fall and the concentrated level will riseWhen a substance such as salt dissolves in water, the substance’s molecules stick with some of the water molecules, so the concentration of the water molecules decreases.  When the water molecules are the same concentration on both sides of a semi permeable membrane and salt is dissolved into one of them, osmosis will occur as shown in the diagram below.                                           Semi permeable membraneWater molecules                                                                   Salt moleculesOsmosis is the movement of water molecules across a semi permeable membrane from a region of high water concentration to a region of low water concentration.  My prediction in this investigation is that the solution with the least salt will

make the potato weigh more, thus the potato in the distilled water solution will weigh the heaviest, because there will be a higher concentration of water molecules in the distilled water than inside the potato cylinder.  Therefore, water will move in from high concentration to low concentration this will increase the mass.  I based my prediction on the process of osmosis, which is a special type of diffusion.  It occurs across a permeable membrane, which allows some particles to diffuse through it and not others.  Most cell membranes are like that, being permeable to water and some solutes only.  Osmosis ...
