What happens to a potato slice in a solution of water that demonstrates osmosis?

the potato slice with decrease in mass, as the free water molecules during osmosis will leave the potato paasing through the semi permeable membrane. This happens because there is more free water molecules on the outsite of the potato, forcing more net movement towards the outside of the potato

∙ 12y agothe water will soak into the potato and show the movement of water from the outside of the potato, into the potato, which will have had less of a concentration inside of it than its surroundings

∙ 13y agowe set up all of the test tubes at once, and labelled them individually to avoid confusion later on. Into each test tube, we poured 15mls of Glucose solution, and added one of the potato chips, each weighing around 1 gram, and measuring 33mm by 5mm. In order to make it as much of a fair test as possible, we added the potato chips very quickly, to make sure one chip didn't have a longer amount of time in the solution than another. We then left each one for 30 minutes.
After 30 minutes, we emptied each test tube, leaving only the potato chips inside. Before we measured and weighed each chip, we dabbed them with paper towel. If we had of left excess water on the chips, the weights would not be accurate. We then measured the chips in grams because they are a more accurate measurement.

∙ 12y agoI've done this experiment in college. you get 4 pieces of potato the same size, and weigh them. you get different moles of sugar solution and put the potato in each of them. you leave the potato in the sugar solution for half an hour and then dry them off and reweigh them
hope this helps :) it's easy but a bit boring x

∙ 14y agoit gets bigger (weighs more) so u measure the mass b4 and after, cos water moves into the potato as it contains a more conc solution thru semi permeable membrane

How does length and width of a potato affect osmosis and also how does the mass of the potato affect osmosis?
If a potato has a larger surface are:volume ratio, it will be affected by osmosis more quickly that a potato with a smaller surface are:volume ratio. Presumably a potato with a larger mass will have a smaller SA:Vol ratio, and as such will be less affected.
Will changing sucrose concentrations change the mass of the potato?
Yes, through a process called osmosis. Osmosis is the diffusion of water across a cellular membrane. Water flows from high concentrations to low concentrations. The mass of the potato will change based on the molarity of the solution it is placed in. CHEMISTRY REFRESHER: molarity is the amount of moles of a substance per liter(of water). If the potato is placed in a solution with a lesser molarity than itself(the solution has less glucose than the potato) then we would expect for the potato to gain water. This is because there is a greater concentration of water outside of the cell wall, so water enters the cell in order to obtain equilibrium. Using the same reasoning we would expect for the potato to lose water if it is placed in a solution of higher molarity
What change will occur if a piece of peeled potato is dropped in a concentrated sugar solution?
The potato may show some shrinking, but the more observable change is loss in mass of the peeled potato. Water will move out of the potato by osmosis. In osmosis, the water moves from the area of higher concentration to the area of lower concentration. There is lower water concentration outside of the potato because of the high amount of sugar dissolved in it. Depending on the concentration differences between the potato and the solution, water loss will continue until an equilibrium is reached. The potato piece will become flaccid (floppy)/plasmolysed, because of the water loss it has suffered. Shrinkage results from loss of turgor pressure in the potato, as a result of it becoming plasmolysed.
What happens when a cell plant is placed in salt. In a potato I made a hole and I put salt on it . In other hand I put this in a cup with water. What will happens in relation a Diffussio aND oSmos?
~When you put salt in potato and then put it in the water cup, there is low water concentration in potato and more concentration in the cup of water. Due to this concentration gradient water moves from the cup into the potato by osmosis.
Analysis in potato in a salt solution?
first place a potato which is carved slightly inwards in the salt solution. it adsorbs the solution slowly and the level of the solution decreases.now place the pin at the potato
Will a potato lose weight if it is peeled and soaked in a salt water solution for a day?
Because of osmosis the water in the potato will move into the hypertonic solution causing the potato to lose weight.
If you put sugar in a peeled potato what will happen?
Osmosis will happen. The water will move from the potato into the sugar solution. The potato will lose mass and shrink.
Why do potato's shrink when you put them in water mixed with sugar?
The water in the cells diffuse out into solution via simple osmosis
What are effect of osmosis on potato strips?
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.
Can peeled boiled potato go through osmosis?
yes peeled potato go through osmosis.
What organism is used in the osmosis experiment?
A potato is used in the osmosis experiment.

What happens to potato strip in dilute water?
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.
How does boiling a potato effect osmosis?
Boiling the potato destroys the cell membrane which is a partially permeable membrane. Thus osmosis is unable to occur as osmosis occurs through a partially membrane and only diffusion would occur.
What happens if you put potato in to a cup of distilled water and salt solution?
God will strike the potato core into oblivion and send it to hell.
