    Aim: The aim of this experiment is to observe how Osmosis takes place, and to see what reactions occur in the two solutions the potatoes will be placed in. Prediction: I predict that the potato that will be placed in the sucrose solution will lose water and therefore the potato will shrink. Si...

    Does glucose concentration affect mass and how? I was shown an example of Osmosis, which involved a potato chip and 5% glucose solution; we saw that as the glucose solution, was left with the potato given 24 hours, the potato had gained mass due to the glucose solution being more concentrated tha...

    Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.[1][2][3] It may also be used to describe a physical process in...

    OSMOSIS IN POTATO Osmosis describes a physical process in which any solvent moves, without input of energy. The word 'osmosis' is particular to the diffusion of water molecules into the cell. These are the ways to see the effects of osmosis on a plant by comparing potatoes placed in different type...

  • Osmosis
    Planning Osmosis is the diffusion of water from a lower concentration of solute to a higher concentration of solute, through a partially permeable membrane. In a high concentration of water the amount of solute (e.g. sucrose) is low. This could be called a weak or dilute solution. In a low co...
