Investigating Whether the Strength of a Salt Solution Affect Osmosis in a Potato

Investigate whether the strength of saline affects penetration of potatoes ======= Factors that may influence the experiment: - Water temperature - Type of potatoes - Melting amount - Dissolution time factor of potatoes: - Percentage of salt in solution preparatory apparatus ==================== 7 beakers (250 ml) 7 kinds of sugar solution strength (100 ml per strength) As follows 1 x 0.0 % Salt 1 x 0.5% salt 1 x 0% salt 1 x 5% salt 1 x 0% salt 1 x 5% salt 1 x 0% salt potato rule cork bowling knife preliminary plan

What I change will be the concentration of the solution that will help you study the penetration of potato tissue, in the investigation of the independent variables (what you change) and the factors that affect penetration. When potatoes were placed in sugar solution placed at different molarity (strength), different sugar concentrations were changed to observe potato results. Dependent variable (what you measure) In this permeation experiment it is measured the change in mass and length of potatoes in different molar concentrations of sugar solution. Record the mass in grams and change the length using a ruler.

In this survey we will study the theme of penetration. This survey is not a simple experiment on potato chips but rather to determine if the theoretical water penetration from a low concentration solution to a high concentration solution can be demonstrated through a partially permeable membrane. We use digital scale to measure the quality of the potatoes before and after. I used a digital scale so it provided a measurement of 0.01 g, which made the results very accurate. Various directions

I predict there is penetration between potatoes and solutions. I think that the length and quality of potato tubers in distilled water will increase, but the quality and length of potato tubers in 100% saline will decrease. Somewhere between the two solutions, there is a salt concentration of potato tubers. There are several reasons why I made the above predictions. I learned about intrusions from previous experiments, and I know that it is a special case of diffusion. The water molecules pass through the partially permeable membrane. In this experiment, a part of the permeable membrane becomes a potato tubular cell membrane and the salt concentration of the potato tubers is examined. I know that water molecules move from high concentration to low concentration when infiltration occurs.
