However, if a potato is submerged into a distilled water beaker or a low sucrose concentrated solution, its size, as well as the mass, will increase.

This thought roots from the natural osmotic movement are solutions such as hypoosmotic, hyperosmotic and isosmotic. Material and apparatus. Six beakers no uncertainty considering they were not measuring beakers and not marked.

Prepared sucrose solutions : 0. The working area was cleared out and a cutting board was placed on the table. Approximately potatoes with a medium size not too small were placed on the cutting board.

With a ruler, sides of the chosen potatoes were measured and reached the length of 4 cm. With a knife, sides of the potatoes were cut and turned into rectangularly shaped potatoes.

Step was repeated until 30 potato chores were made. A piece of tape was put on each beakers side and with a pen, each was labeled on the tape according to what concentrated sucrose solution they were going to contain.

After each tag on the beakers, the written sucrose solution on the beakers was poured until they all were half full. After 24 hours the potato chores were brought out of the solutes and then the final lengths were measured.

Initial observation. The potatoes were generally :. Final observation. The potato chores were out of being submerged in different sucrose solutions for 44 hours and were soggy and soft.

The average size change between sucrose concentration 0. A further consolidation of the hypothesis, results, and the background information is how the potato chores in distilled water and in the sucrose solution 0.

A wide range of errors can be kept in consideration when it comes to the measurement of temperature, potato chores and the fact that we manually kept on touching the potatoes with our hands which could have defected the sugar distribution across the potatoes surface and altering the osmosis results.

Another error factor would also be the fact that more than one potato was required in the experiment to get the 30 potato chores, thus us having several different sucrose sources and by the fact that each potato has different levels of nutrition, the results might have a deficiency inaccuracy in this area.

Erika Steele. Elysia Northall. Biology Junction. Recent Posts See All. Neuroscience's Say On Free Will. Osmosis can be demonstrated when potato slices are added to a high salt solution.

The water from inside the potato moves out to the solution, causing the potato to shrink and to lose its 'turgor pressure'.

The more concentrated the salt solution, the bigger the difference in size and weight of the potato slice.

In unusual environments, osmosis can be very harmful to organisms. For example, freshwater and saltwater aquarium fish placed in water of a different salinity than that to which they are adapted to will die quickly, and in the case of saltwater fish, dramatically.

Another example of a harmful osmotic effect is the use of table salt to kill leeches and slugs. Essentially, this means that if a cell is put in a solution which has a solute concentration higher than its own, it will shrivel, and if it is put in a solution with a lower solute concentration than its own, the cell will swell and may even burst.

Chemical gardens demonstrate the effect of osmosis in inorganic chemistry. As mentioned before, osmosis may be opposed by increasing the pressure in the region of high solute concentration with respect to that in the low solute concentration region.

The force per unit area, or pressure, required to prevent the passage of water or any other high- liquidity solution through a selectively permeable membrane and into a solution of greater concentration is equivalent to the osmotic pressure of the solution , or turgor.

Osmotic pressure is a colligative property , meaning that the property depends on the concentration of the solute, but not on its content or chemical identity.

The osmotic gradient is the difference in concentration between two solutions on either side of a semipermeable membrane , and is used to tell the difference in percentages of the concentration of a specific particle dissolved in a solution.

Usually the osmotic gradient is used while comparing solutions that have a semipermeable membrane between them allowing water to diffuse between the two solutions, toward the hypertonic solution the solution with the higher concentration.

Eventually, the force of the column of water on the hypertonic side of the semipermeable membrane will equal the force of diffusion on the hypotonic the side with a lesser concentration side, creating equilibrium.

When equilibrium is reached, water continues to flow, but it flows both ways in equal amounts as well as force, therefore stabilizing the solution.

Reverse osmosis is a separation process that uses pressure to force a solvent through a semi-permeable membrane that retains the solute on one side and allows the pure solvent to pass to the other side, forcing it from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.

Osmosis may be used directly to achieve separation of water from a solution containing unwanted solutes.

A "draw" solution of higher osmotic pressure than the feed solution is used to induce a net flow of water through a semi-permeable membrane, such that the feed solution becomes concentrated as the draw solution becomes dilute.

The diluted draw solution may then be used directly as with an ingestible solute like glucose , or sent to a secondary separation process for the removal of the draw solute.

This secondary separation can be more efficient than a reverse osmosis process would be alone, depending on the draw solute used and the feedwater treated.

Forward osmosis is an area of ongoing research, focusing on applications in desalination , water purification , water treatment , food processing , and other areas of study.
