Investigate the effects of different concentration of sucrose solution on the mass of potato cells

The aim of my Investigation is to find out how the mass changes in the different solutions

       

I am investing how the mass of a potato different concentration of solution of sucrose.  The only thing that I can control is the different concentration of sucrose solution in each beaker.

The Independent variable the thing that I will be changing in this investigation. The concentrations of the solution with potato tissues. The different sugar concentrations will be changed to see the result of the potatoes when placed in sucrose solutions

My dependent variables are the change of mass in the potato chips.  

The other variables that I must control are…

  • Temperature: because the temperature could affect the kinetic speed of the water molecules, so the solutions must be kept at the same temperature.
  • I would also be required to control the amount of liquid added to the beakers, I had used 10cm3 in each of beakers.  
  • The same person would have to do the experiment so that there would be no human errors, because the other person might not leave of at the same place, as the perverse person thus making a mistake in may be the measurement of the sucrose solution.

I think that the potato chips which were submerged in the weak sucrose solutions eg: 0.0M, 0.2M, 0.4M will increase in mass.

The potato chips which were submerged in the strong sucrose solutions eg: 0.6M, 0.8M, 1.0M will decrease in mass.

The glucose molecules try to diffuse to the outside but cannot get through the potato cells membrane because the pores are too small.  Water molecules diffuse through the pores down a concentration gradient.

 

In a solution of 1.0M were there is ...
