The Effect of Various Solutions on the Size of Potato Pieces

Impact of various solutions on the size of potato blocks - I found that in various solutions the size of the potato pieces changed. Investigation plan ---- Variable variables I can change only one at a time, but I will change a lot. This is a list of things I can change; • Sugar / salt concentration in solution • Potato size • Solution volume • Changing solution temperature variable I will change the concentration of sugar in solution.

In this survey, my goal was to discover the moisture potential and solute potential of potato tissue paper. I will put potato pieces of the same size in different sucrose solutions and check the rate of change of mass. Next, plot the results on the chart and calculate the intercept of the most fitting line through the x-axis (sucrose solution concentration). This will give me the potential water of potato tissue paper, that the quality does not increase and decrease, and that the cells are in equilibrium.

To verify my hypothesis, I will conduct an experiment to investigate the effect of salt solution on potato tubers. I put the potato pieces in different saline solutions. Measure the length and quality of potato tubers before and after the experiment. From that result, you can know the salt concentration of potato tubers. The results I gather will allow me to achieve the purpose of the experiment, because they will tell me to show potato salt concentration. They will do this because you will see if the tubers are slack (soft and durable), which means that the salt concentration of the solution is higher than the concentration of the potatoes. When they swell (hard and straight), the salt concentration of the solution is lower than the potato salt concentration. Find the moisture concentration of potatoes by finding that no two sets of potato tubers begin to lose it as it no longer accepts permeate.

If you add potato slices to a high concentration salt solution (hypertonic), infiltration is very effective. The water from the inside of the potatoes is removed from the potato cells into the salt solution, whereby the potato cells lose the inflation pressure. The higher the concentration of the salt solution, the greater the difference in size and weight of the potato slice after separation of the plasm. Penetration is very detrimental to organisms, especially organisms without cell walls. For example, when saltwater fish (whose cells are isotonic with seawater) are placed in fresh water, the cells will take up and dissolve excess water, and the fish will die. Another example of harmful penetration is the use of salt to kill slurs and snails.
