Photosynthesis

I. Title: Objectives: At the completion of this laboratory you should be able to expose the apparatus of osmosis Describe the mechanism of diffusion Describe how a solute size and molar concentration affect the bunt of osmosis done a selectively permeable membrane squander a clearer understanding of the terms : hypertonic and hypotonic II. priming Diffusion is the process by which molecules spread from areas of high concentration, to areas of junior-grade concentration. In this essay we will use dialysis bags in regulate to investigate the blood between the movement of the solute and the solvent and therefrom of the distinctive mechanism of osmosis and diffusion. The solute used will be Methanole a type of provender coloringing.A fodder coloring is any plaza that is added to food or drink to change its color. intellectual diet coloring is used both(prenominal) in commercial food occupation and in interior(prenominal) cooking and also used in a phase of non-food applications for educational purposes. We will measure the movement of the food color and of piss with the use of spectrophotometer. A spectrophotometer is a imposture that measures loose intensity as a function of wavelength. It does this by diffracting the kindling beam into a spectrum of wavelengths, detecting the intensities with a charge-coupled device, and displaying the results as a graph.

There are various types of spectrophotometers for different purposes. A spectrophotometer uses a glint and a prism to bounce light dispatch the sample. III. Research Question: How is diffusions affected by different aqueous environments? IV. Hy! pothesis: V. Materials 6 same size beakers Distilled water Food color Spectrophotometer 2 pipettes 6 dialysis bags 4 cuvettes 1 piston chamber VI. Procedures In this lab you are to front set up the different solutions and then begin enter the data in the provided data table. This experiment will bear two parts. In part one you will...If you want to cross a dependable essay, order it on our website: BestEssayCheap.com
