Aim: To check over how concentration effects osmosis on white potato vine
chips.
Introduction:
I have been asked to investigate the effect of osmosis on potato chips. Osmosis is the diffusion of body of water from a lower concentration of solute to a extravagantlyer concentration of solute, with a membrane.
I have chosen to investigate the effect of the water potential/concentration of solution on potato chips. This factor that I pass on put potato chips into sucrose solutions of varied concentrations. These concentrations would be ones such as these; 0molar, 0.2m, 0.4m, 0.6m, 0.8m, 1.0 and distilled water.
There are other factors pertain and these are;
1) Temperature
2) Water potential of potato initially
3) Size of potato
4) lightsomeness intensity
5) Mass of potato dependent variable
6) Volume of solution potato chip is in
7) Type of potato
8) Time left in solution
9) step up area of potato chip
10)Use the same balance to measure chip
Osmosis is the military campaign of water down a concentration gradient done with(predicate) a partly permeable membrane.
Osmosis through a partially permeable membrane continues until the concentration of water on all side of a membrane is equal.
Osmosis is a special mixture of diffusion; it happens when a membrane has tiny holes in it, which allow water molecules through but stop larger molecules, equivalent sugar. A membrane like this is called semi-permeable.
This experiment shows osmosis: -

because osmosis is the movement of particles from a weak
concentration to a strong concentration through a semi permeable membrane the water will move from the beaker into the visking tubing.
