Investigate the factors affecting the rate of Osmosis

Investigating factors that affect the rate of invasion planning is the diffusion of water from a low concentration of solute through a partially permeable membrane to a high concentration of solutes. For high concentrations of water, the amount of solute (eg sucrose) will be less. This can be called a weak or dilute solution. For low concentrations of water, the amount of solute increases. This is a powerful or centralized solution. When the partially permeable membrane splits such two solutions, the water moves from the high concentration region to the low concentration region until the sides are equal.

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

Research Factors That Affect Reaction Rate 1.0 Introduction Reaction rates are indicators of the amount of reactants used or the rate at which products are produced. There are many factors that influence the reaction rate between the two reactants. They are the surface area of ​​potato chips, liquid temperature, catalyst, light, physical agitation and liquid concentration. - Nematode Caenorhabditis elegans is a free-living nematode that lives in organic-rich soil and feeds on bacteria and other microorganisms (Edgley, 2000). The nematode Caenorhabditis elegans has the advantage of becoming a complex animal with nerve, reproductive and digestive system, but it is an excellent model organism for studying aging because it is small enough to handle like a microorganism
