An Investigation Into the Effect of Sucrose Concentration On Osmosis in Potato Chips
My aim is to investigate the amount of osmotic activity between a
potato chip and different concentrations of sucrose.
The following affect the rate of osmosis:
Temperature
The warmer most things are the more quickly particles move, therefore
increased temperature will increase the rate of osmosis. So, if a
potato chip is in a highly concentrated solution the water molecules
will quickly leave the chip because of the increase in temperature or
if the chip is in a high water concentration the water molecules will
go inside the chip.
Time
The longer you leave the potato chip in the solution, more osmosis
will occur, so the greater the change in mass in the potato chip.
Surface Area
If the surface area of the chip is large, there would therefore be
more space for osmosis to occur, so the greater the change in mass in
the chip.
Concentration of Sucrose
As the concentration increases the mass of the chip decreases. This is
because the chip has a higher water concentration and the water leaves
the chip and goes to the sucrose solution which has a low water
concentration.
If the concentration of sucrose decreases the mass of the chip
increases. This is because the chip has a lower water concentration
and the water goes inside the chip.
Type of Potato
Different potatoes have different cell sap concentrations. So as each
potato has different cells these cells will affect the rate of
osmosis.
Osmosis is defined as the net movement of water molecules from a
region of high water concentration to a region of low water
concentration through a partially permeable membrane.
I predict that when the water concentration is low in the potato chip,
the water will go inside the tissue of the potato, and the potato chip
will gain weight. If there is very little difference in the two water
concentrations there would only be a slight change in mass and if
