(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

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

was first determined. Acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The hot solution was filtered and the filtrate‚ cooled slowly in an ice bath as crystals started forming out. As the compound crystallizes from the solution‚ molecules of other compounds were excluded from the crystals to obtain pure acetanilide.

Effects of temperature manipulation and solution treatment on the Beta vulgaris craca plant cell membrane and the change of the concentration of betacyanin when placed under these various stresses Introduction: The Beta vulgaris craca plant‚ commonly referred to as the beet root contains a pigment‚ red in colour‚ called betacyanin. The betacyanin’s containment within the cells of the beet root cell relies on the stability of the plant’s membrane structure. The manipulation of the cell’s membranes
