    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

    conduct my experiment‚ I measured 10g of ascorbic acid powder and mix it within 1 litre of water. I believed that by having the solution prepared before putting in the d-block elements would save time overall. Unfortunately‚ the data was all over the place‚ this is because the later I conduct the experiment‚ there is a higher chance of oxidation occur in the ascorbic acid solution as it have a direct contact with oxygen in the atmosphere. In order to keep constancy‚ I had to reduce the amount of ascorbic

    buffer was made. We began this experiment by measuring seven constant amounts of 1ml of 0.1% catechol using a 1 mL pipet into each seven cuvettes. The catechol is our substrate solution. Next‚ different amounts of phosphate buffer ph.6 of 0.5ml‚ 1.0ml‚ 1.5ml‚ 2.0 ml 2.5ml‚ 3.0ml and 4.0ml were added to each of the solution of the 0.1% catechol. The purpose of adding phosphate buffer pH6 is to maintain the particular ph6 for the polyphenol-oxidase (enzyme)‚

    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. INTRODUCTION Recrystallization‚ referred to as the second crystallization‚ is a method

    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

    standards. Further‚ I learned more about the molarity of aqueous solutions‚ and how that quantity‚ along with the volume of the solution‚ can be manipulated to find the exact number of moles in a given volume. In this case‚ experimenters were given aqueous solutions of NaOH and CaCl2 in known molarities and then had them react with one another to yield a precipitate of Ca(OH)2. The precipitate was filtered out of the remaining aqueous solution of stoichiometry. In our case‚ all four tests yielded more
