can only be seen with a microscope‚ so you are going to use sticks of potato tissue in solutions that have different concentrations of dissolved substances to observe the effects of osmosis on living tissue. There are three basic relative concentrations of solutions. An isotonic solution has a concentration of dissolved particles equal to that of cells or body tissues; no net water flow occurs. A hypertonic solution has a lower concentration of water (higher concentration of dissolved particles) than

(As The Editors Of Encyclopædia Britannica say “Paper chromatography‚ technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper. The method consists of applying the test solution or sample as a spot near one corner of a sheet of filter paper. The paper is initially impregnated with some suitable solvent to create a stationary liquid phase. An edge of the paper close to the spot is then immersed in another solvent in which

Materials Water Salt Baking Soda Regular LifeSaver hard candy Cups Watch settled for 5 minutes Observations The Lifesavers are round shape‚ purple color‚ solid and hard and 2cm size. Water is clear at room temperature. Salt and Baking Soda are in it solid state with power appearance. Question Which solution will dissolve the LifeSaver the most within five minutes? Hypothesis

An isotonic solution has the same osmolarity as a tissue. A hypertonic solution has a higher osmolarity and a hypotonic solution has a lower osmolarity. If samples of a tissue are bathed in hypertonic and hypotonic solutions‚ and measurements are taken to find out whether water enters or leaves the tissue‚ it is possible to deduce what concentration of solution would be isotonic and therefore predict the results of osmosis in different

called hypotonic solution and hypertonic solution. Hypothesis: My Hypothesis for diffusion that the starch solution will be hypotonic and diffuse into potassium iodide (IkI). Hypothesis for osmosis is that each of the individual dialysis bags will increase because of the different concentration of the solutions. Which makes this and hypotonic experiment. Hypothesis for this experiment is that each of the four cylinders of potato will decrease in mass‚ because of the solution/concentration

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. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2) A beaker 3) A cork borer 4) A Knife Safety

moving in one direction equals to the amount of molecules moving in the other direction. There are three types of solutions to diffusion: isotonic‚ hypertonic‚ or hypotonic. When the solutions have the same concentration of solutes‚ they are isotonic. When the solutions differ in their solute concentration‚ the solution with more solute is hypertonic to the other solution. The solution that has less solute is hypotonic
