report: Topic: Osmosis of potatoes in different sucrose solutions. The aim of this experiment is to test whether more water moves out of a potato when it is placed in a sweeter sucrose solution than a potato in a less sweet solution. The hypothesis of the experiment is that we expect more water to move out of the potato placed in the sweet solution than the potato placed in a less sweet solution. Independent variable: concentration of sucrose‚ concentrations: pure water H20‚ 0.1 M‚ 0.5M‚

The aim of this experiment is to better understand the process of fermentation of yeast in different concentrations of sucrose. The experiment worked with yeast and sugar (sucrose and glucose) to determine the rate of fermentation by testing the pressure of C02 in the test tube. The experiment tested the metabolic capability of yeast anaerobically meaning no oxygen was present (this was ensured by the thin layer of oil on the top of the solution). This means that the metabolic rate of the yeast could

Karmini Mondal Chemistry 245- 061 Biosynthesis of Ethanol from Sucrose Introduction: Ethanol can be created using two methods: acid catalysed hydration of ethylene and through fermentation of sucrose. The purpose of this experiment was to use fermentation to produce ethanol from commercial sucrose (store-bought sugar)‚ using fractional distillation of the fermented solution. The percent ethanol in the fermented solution was then calculated. Mechanism: Results: Mass of conical vial 10.36 g

Extraction The first stage of processing is the extraction of the cane juice. In many factories the cane is crushed in a series of large roller mills: similar to a mangle [wringer] which was used to squeeze the water out of clean washing a century ago. The sweet juice comes gushing out and the cane fiber is carried away for use in the boilers. In other factories a diffuser is used as is described for beet sugar manufacture. Either way the juice is pretty dirty: the soil from the fields‚ some small

The Effect of Osmosis on Differences of Amount of Sucrose Osmotic Pressure and its Influence on the Concentration of Sucrose in Solution Brennan Montoni Movement of molecules and Ions Names of Lab Partners Biology 110 March 23‚ 2011 Code of Academic Integrity INTRODUCTION: During the process of osmosis‚ water will move across a differentially permeable membrane. The water will transfer from a region of lesser solute concentration to a region of greater solute concentration

Determining the Rate of Osmosis with Water and Sucrose 10/3/2012 Determining the Rate of Osmosis with Water and Sucrose Author: Results: Bag 1 had a rate of osmosis equal to 0.01 grams per minute. Bag 2 had a rate of osmosis equal to 0.0543 grams per minute. Bag 3 had a rate of osmosis equal to 0.0471 grams per minute. Bag 4 had a rate of osmosis equal to 0.0886 grams per minute. Bag 5 had a rate of osmosis equal to -0.0914 grams per minute (Figure A). Figure A: Shifting of mass

Sucrose Metabolic Syndrome Induced Metabolic syndrome was induced from birth to eighteen weeks of life‚ by drinking a sucrose solution 35% ad libitum‚ which ensured that all main manifestations of the disease were developed. Three females and one male with sucrose-induced metabolic syndrome were mated. Likewise‚ we

Experiment1Separation of mixtures by filtration and crystallisationBackgroundThe separation of a mixture of two solids can often be achieved by filtration and crystallisation. To be successful‚ this requires that the components of the mixture have different solubilities in a particular solvent.

Christine Otieno Estimating Osmolarity of plant Cells(potato and celery)by percentage change in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease
