Investigating the Equivalent Molarity of Potato Tissue Compared to Sucrose Solutions

Investigation of equimolar potato tissue Compared to the sucrose solution scheme, permeable membranes occur on semipermeable membranes at different concentrations on both sides of the membrane on semipermeable membranes and the cells swell (as water enters them) It is known to dissolve (as water flows out) and therefore changes their amount. Our goal was to change the length of the potato chips soaked in the sucrose solution and try to find an equivalent molar concentration.

For 1 molar sucrose solution, I think that the weight loss of the potato pieces is the most significant change compared to the previous 0.8, 0.6, 0.4, 0.2 and 0 mol solutions. This is because the concentration of the solution around the potato piece is much higher than the solution in the potato cell, so the moisture entering the potato piece cell liquor increases. Independent variable: The independent variable is to be changed by experiment, in which case the concentration of each solution will be from 0 mol to 1 mol as described above. The reason for changing the concentration is to observe the effect on potato pieces when placed in different molar concentrations of sucrose solution.

I am doing this experiment to understand what is happening during diffusion of semipermeable membrane. Our hypothesis is that if the molarity in the sucrose solution is high the potatoes lose their mass and if the molarity in the sucrose solution is low the potatoes are of good quality. We understand how diffusion and semipermeable membranes allow specific molecules to pass through it. Diffusion is the behavior of molecules that passively pass through a semipermeable membrane. This diffusion helps to tune the cellular processes that are performed periodically so that the cells can survive and function.

Solute potential can be determined by determining the molar concentration of sucrose solution that contributes to the balance of solution and potato cell content. Where i is the ionization constant and C is the molar concentration per liter of sucrose. Equilibrium, R is the pressure constant (0.0831 l bar bar / mole K), and T is the temperature of the solution (Kelvin). Firstly, 160 to 170 mL of distilled water was poured into the cup, about 4 mL of IKI solution was added to water and mixed well. The initial color of the solution was recorded in Table 1. The glucose specimen was then immersed in the solution and the initial glucose test results of the solution of Table 1 were recorded using the + sign to indicate the positive result of glucose. Negative consequences for glucose. After finishing, I threw out the used glucose test strip.
