The effect of ribena concentration upon osmosis in a potato: evaluation posted on november 8, 2016 to conclude, it is clear from this experiment that the greater the concentration of a ribena solution, the greater the loss of both mass and length in a potato chip. In this case study i will be looking at how osmosis affects a potato chip my aim is too investigate the effect of varying concentrations of certain salt solutions, and water, on the amount of osmotic activity between the solution and a potato chip of a given size and mass. Effect of osmosis on potato chips osmosis is a special kind of diffusion involving the movement of water through a semi permeable membrane, separating solutions of different concentrations the water passes from a region of high concentration to a region of low concentration until the two concentrations are equal in water. Aim: to test the effects of osmosis of living tissue hypothesis: the mass of potato chip will be effected by the concentration it is kept in dependent- the mass of the potato chips independent- concentration of sucrose control- potato chip size method: 1) cut suitably sized slices or cylinders of show more aim: to test the effects of osmosis of living tissue.
Science experiments on the osmosis of a potato by tricia lobo updated april 26, 2018 osmosis, the process in which solvent molecules move from an area of lower solute concentration to an area of higher solute concentration, can easily be demonstrated with potato experiments. Science coursework aim: to investigate how concentration effects osmosis on potato chips introduction: i have been asked to investigate the effect of osmosis on potato chips osmosis is the diffusion of water from a lower concentration of solute to a higher concentration of solute, through a. Ib biology ia: osmosis - free download as pdf file (pdf), text file (txt) or read online for free the effect of increasing sucrose concentration on the mass of potato chips biology was an hl subject for me. Gcse biology: osmosis in a potato aim to investigate the effect of placing a piece of potato in a 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.
Practical investigate the effect of solute concentration on osmosis in potato chips scientists investigate the effects of osmosis on living cells. I have used potato chips, distilled water and sucrose solution to check the rate of osmosis in potato chips when distilled water and different concentration of sucrose solution is added i have used scalpel to cut the potatoes in the size i need and also used to make the surface equal of all the potato chips. Effect of osmosis on potato chips osmosis is a special kind of diffusion involving the movement of water through a semi permeable membrane, separating solutions of different concentrations. Effect of the effect of osmosis in potato cells introduction i am doing an experiment to find out the effect that osmosis has on water solution and a sugar solution 2 / 451 effect of osmosis on potato chips. Potato chips with higher surface will mean that osmosis occurs faster, because more of the potato is available for reaction time: in order to find out how concentration affects osmosis the amount of time which the potato will be left in a solution should remain constant.
Prior to the experiment we carried out a short pilot test, using potato chips and solutions of strength 00, 10 and 20 molar solutions the chips were 25mm in length each, and each chip was placed in 5 cm3 of either distilled water/10 molar / 20 molar sugar solutions and left for 30 minutes. Percentage of change in mass is decreasing thusly we can conclude thatthe difference of the initial from the final and as it gets greater thatmeans the mass of the potato changed massivelyaccording to the osmosis theory as the concentration of the sucrosesolution increases the particle’s water potential increases and becomeshigher than the. Hypothesis: when potato chips are placed in solutions with high concentrations of sugar (for example 08 mol l-1) then they will lose mass as the chip will lose water because of osmosis. So because of osmosis the water in the potato will leave to become equilibrium with the sucrose concentration if the concentration of sucrose is low in the solution, then the potato’s mass will change less because it has more water than sucrose.
Potato and osmosis investigation planning aim: to investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Investigate the effect of varying solution concentration on osmosis in a potato chip prediction a definition of osmosis is: 'the movement of water molecules from an area of high water concentration to a low water concentration across a semi-permeable membrane' (oxforddictionary 2000. We will write a custom essay sample on biology coursework: effect of sugar solution on potato chips specifically for you the more the potato will expand by osmosis when the concentration of water is identical to the concentration of the potato cell, there will be no increase or decrease in weight effect of sugar solution on potato.
Quick answer potatoes lose weight when placed in high concentration sucrose solutions because they lose water through osmosis osmosis is the process where solvent molecules pass through semi-permeable membranes to equalize the solute concentration on both sides of the membrane. When carrying out the experiment i used a range of 0, 02, 04, 06, 08 and 1 molar solution to see the effect of osmosis in the potato pieces in the future i would like to have more varied range of the concentration of the solution in order to produce a more varied range of results ie 0, 01, 02, 03. Osmosis coursework how does the amount of sugar in a water solution affect the process of osmosis in potatoes introduction in this experiment, i will be looking to investigate the effect of varying concentration of a sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size.
