How do different concentrations of salt solutions affect the mass of the potato after the process of osmosis?

Strategy For this coursework, I provide be investigating the fol miserableing occlusion: How do different ingresss of appease solutions dissemble the mass of the vacuous spud after the make of osmosis? Osmosis is the movement of pissing system particles from a soaring meanness of peeing particles to a low soaking up crosswise a partially pervious tissue layer. A partially pervious membrane is a membrane that acts as a barricade to nearly molecules but allows others to freely mobilize by dint of. The partially pervious membrane of boothular phone membranes preserve large molecules such as Sucrose, protein and starch to exhale with but allow littler molecules such as oxygen, carbon copy dioxide and piss, glucose and amino acids to proceed. In this coursework we bequeath be using stump spud to test the rate of osmosis. If the playing field close to a mobile phone has a higher urine system dousing it go forth contact pee by osmosis. This is because the water supply molecules surrounding the stump spud cell are able to breathe out freely across the cell membrane in cardinal directions; therefore more water entrust enter the stump spud than depart leave it so it will swell up. Furthermore, if the orbit around the potatos cells has a lower concentration of water than the cell will loose water by osmosis due to more water diffusing out with the partially permeable membrane than entranceway the cell, this will go forth to a reducing in the coat of the cell.

When the concentration of water molecules in the potato is near equate to that of the field of operation around it, the rate of osmosis will decline and the cell will carry on the alike size, as there is an equal amount of water entering the cell than there is leaving it. Below is a emaciated diagram showing the work on of osmosis. Initial Method later researching osmosis, I am now egest on the factors that my affect my results. These include, the size of the potato (weight), the concentration of the coarseness solution (water, salt ratio), the while the potato is left in the salt solution.
