Osmosis in Potato Chips

Potato Chips Penetration Preliminary Experimental Study Transmittance 1M Sugar 50: 50 0M (W) Initial Quality 40 05 34 Final Quality 01 85 43 Quality Changes -0.39 -0.21 0.09% Quality Changes -12.5% ​​- 10.5% 84% Evaluation Results We Preliminary experiment which made it possible to obtain better results for actual experiment of. For example, through experiments, we learned something from experiments.

Investigate the effect on the weight of the 5 x 30 mm King Edward chip in case of infiltration. The invasion is the movement of water from the high concentration region through the semipermeable membrane to the low concentration region. To do this, I put chips in different salt concentrations and compare the weights before and after. To make this test fair, make sure each chip is ready for 20 minutes. Make sure the potatoes are dry before weighing. Furthermore, determine the length of the chip as accurately as possible and do not process the chip. Therefore, it does not affect the heat.

Experimental introduction and experimental method: Study of influence of salt concentration change on potato tissue invasion

This figure shows the difference in weight percentage of permeation occurring in potato chips. Since the average weight loss of three potato chips was 7, indicating maximum penetration occurred, the initial rate was highest. As my hypothesis predicts, the interest rate starts at a high level and gradually declines until it stops thereafter. However, from this figure you can see how invasion starts rapidly and then decreases to nearly constant permeation rate. There seems to be the same amount of penetration occurring within 8 minutes. You can further penetrate to the last stop

I think that the penetration rate of each potato is about the same. Since some potatoes have different textures, the results will not be exactly the same. I think that the color of potato chips may affect penetration rate. From past experiments, I think that the average mass loss per chip is about 0.25 g and the length is 4 mm. The longer the potato is in solution, the greater the mass until all the solution is absorbed into the potatoes.

As my chart clearly points out, the penetration is very obvious as the quality of the chip varies from solution to solution. With three concentrations (distilled water, 0 and 5 moles), potato chips gained quality. Potato chips can be thought of as absorbing water particles from three solutions. This clearly supports the theory of penetration. In addition, there are two solutions (2 and 5), and the chip degrades the quality. This is to escape the solution from the tip and get balanced water. The interesting result I got was the result of 5 molar solution. Since this figure shows no difference in quality, we can conclude that the water concentration of the potato cell is the same as that of the surrounding solution. Before starting the experiment, equilibrium was reached
