The Effect of Sugar Solution on the Mass of Potato Chips Aim - The aim of this experiment is to find how changing concentrations of sugar solution affects the mass of potato chips. Plan ==== Preliminary Work ---------------- In my preliminary experiment my aim was to find out what the optimum length of potato chip would be to use in my actual experiment. My experiment consisted of using three off 2 cm's of potato chip and three off 3 cm's of potato chip. I only placed them
The Molarity of Sugar Solution Inside Potato Cells Background Information Osmosis Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. Semi- permeable membranes are very thin materials which only allow certain things to pass through them. They will allow small molecules like Oxygen, water and Carbon Dioxide to pass through. Water molecules can pass across the cell membrane in both directions
Investigating the Effect of Sugar Solution on the Weight and Size of Potato Cells Aim: To investigate whether the different concentration of sugar solution will affect the weight and size of the potato cells. General background information: Osmosis is defined as the movement of water or any other solution's molecules from an area in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane
Testing Osmosis From a Sugar Solution to a Potato Introduction: Osmosis is the passage of water molecules from a weaker solution into a stronger solution through a partially permeable membrane. In this case, Osmosis applies to our practical because we are trying to see if a sugared solution has an effect on potatoes. Prediction: I predict that the higher the sugar concentration, water will transfer from the potato into the sugared solution making the potato decrease in weight,
Investigating the Effect of Different Concentrations of Sugar Solutions on Potato Chips Aim: - To investigate the effect on potato chips in different concentration of sugar solutions. Introduction: - Osmosis is the net movement of water molecules from a region where there is a higher concentration of water molecules to the region where there is lower concentration of water molecules. The water molecues move through a partially permeable membrane, which allows the smaller molecules
Investigation to Determine the Effect of a Range of Different Concentrations of Sugar Solutions on the Potato Cells Aim My aim is to set up an investigation to determine the effect of a range of different concentrations of sugar solutions on potato cells. I predict that the higher the concentration the more the length and mass of the potato chip will decrease. The lower the concentration the more the length and mass of the potato chip will increase. This should happen due to the law
Effect of Different Sugar Concentrations on Benedict's Solution PLANNING: Hypothesis and prediction: My hypothesis is that the sugar solution with the highest concentration will turn the precipitate the darkest colour. This will be the 10% sugar solution. This is because the more amount of sugar it contains the more it will reduce the Copper. It will be a much darker precipitate compared to the other two. Background theory: Benedict's solution is an aqueous solution of Copper (II) Sulphate
An Investigation Into the Effect of Sucrose Concentration on Osmosis AIM: The aim of my experiment is to investigate the effect of sucrose solution on osmosis in potato cells, and what the point of equilibrium would be. I shall be observing how the mass of the potato chip changes in five different concentrations of glucose solutions. HYPOTHESIS: Osmosis is the diffusion of water molecules from a high water potential to a lower water potential through a partially permeable membrane
Prediction: I predict that the potato cylinder in the lowest sugar solution (water) will gain the most mass through osmosis, whereas the 80% sugar concentration will lose the most mass through osmosis. I predict this because I think that the potato chips will try to gain and lose water between the two sides of its cell wall in order to reach an equilibrium between them. Because the 80% sugar solution has a high amount of sugar molecules, which can not diffuse through the membrane, I think
-I predict that the weight of the potato in the sugar solution will decrease and the weight of water will increase. I predict that the weight of the potato in the sugar solution will decrease when it reaches 3:1 (salt: water). In put Variables: -Molarity -Size of potato -Mass of Water -Molarity of Sugar -Length of time in the solution -Temperature of water Out put variables: -Weight of potato Key variables: -Molarity of sugar. This is a key variable because it has the most
concentration of sugar solution on Osmosis in potato tubes. Key factor: In the investigation we change the sugar solution from: 0%-10%-20%-30%-40%-50% this is the independent variable; the dependant variable is the change in mass. Prediction: I predict that all the potato tubes in pure water or low concentration sugar solution will swell because water enters their cells by osmosis. The potato tubes in higher concentration sugar solution will shrink
hands. After, we will get another beaker and pour some 1% sugar solution in it. When we have done this, we get one end of the visking tube and 'ruffle' it, then we get some string and one person will tie the end of the tube, while the other person hold it. The visking tube then will go back in the water, while we get a dropper and the beaker of sugar solution. After we will use the dropper to slowly and neatly pour the 1% sugar solution in the visking tube; we will fill it up ¾ of the way. Then
potato chips placed in different concentration solutions of sugar , the factor we are going to change in the experiment is the concentration of sugar in each solution. I am going to investigate the movement of osmosis through a semi permeable membrane. Prediction I predict that in my experiment the rate of osmosis will decrease as the amount of sugar in the solution increases , I predict that when the potato chip is placed in the sugar solution the water inside will leave due to osmosis
put into the solutions, water will pass from the weaker solution into the stronger solution. For example, when a potato chip is put into distilled water, the water will pass from the distilled water into the potato cells, making it more turgid because the cells now have more water in them. When a potato chip is put into 1M sugar solution, the water from the potato cells will pass into the sugar solution because the solution inside the potato cells is weaker than the solution in the test tube
given strength of sugar solution. Prediction I predict that, as the solution becomes more concentrated the more the cell will shrink, as the water, of higher concentration inside the potato cells, flows down a concentration gradient into the solution, which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict that when the solution is 0.5M the percentage change will be 0.5x%, and when the solution is 0.25M strength
concentrations of sugar solution on potato cells. Variables: The variables are; the concentration of sugar in the solution and the mass of the potato cylinder. We will measure the mass of a potato cylinder after a certain amount of time in a certain solution. Fair test: To keep the test fair we need to keep the controls the same. Like keeping the temperature the same so the kinetic energy doesn't cause a faster reaction. Prediction: I think that if the solution is more concentrated
Osmosis When a substance such as sugar dissolves in water, the sugar molecules attract some of the water molecules and they stick to the sugar molecules. This means that there are fewer free water molecules in the solution. When two different sugar solutions come into contact with each other through a partially permeable membrane the free molecules can go through the membrane easily but the sugar molecules are too big. If one of the solutions has more free molecules than the other then
an enzyme-controlled reaction. Using amylase and starch as my example. Introduction: I am investigating the effect of the concentration of the enzyme, amylase on the time taken for the enzyme to fully breakdown the substrate, starch to a sugar solution. The varied variable will be the concentration and all other variables are going to be fixed. The different concentrations will be: 0.5% 0.75% 1.0% 1.5% 2% An enzyme is a class of protein, which acts as a biological catalyst to speed up
Concentration on the Mass of Potato Tissue Prediction: I predict that a high sugar solution will cause the mass of the potato to decrease. This will be due to osmosis. Osmosis is the diffusion of water from a region of high concentration to a region of low concentration across a semi-permeable membrane, such as the one of the potato. If the water concentration inside the potato is higher than the water concentration in the solution then the cell will lose water through osmosis, which will cause it to shrivel
when you put it onto different sugar solutions? A sugar solution is made from glucose and water. A raisin is a dried grape. A sugar solution is inside a grape. Prediction In a weaker sugar solution the water goes in, so the mass increases. In a stronger sugar solution the water goes out, so the mass decreases. In a weaker sugar solution the raisin’s mass increase caused by osmosis, the particles are absorbed by the raisin. In a stronger sugar solution the raisin’s mass decreases, also
