Objectives: At the completion of this laboratory you should be competent to รข€¦
Describe the apparatus of osmosis
Describe the mechanism of diffusion
Describe how a solute size and molar concentration affect the abut of osmosis done a selectively permeable membrane
Have a clearer understanding of the terms : hypertonic and hypotonic
II. Background
Diffusion is the process by which molecules spread from areas of high concentration, to areas of low concentration. In this essay we will use dialysis bags in order to investigate the blood between the movement of the solute and the solvent and therefore of the distinctive mechanism of osmosis and diffusion. The solute used will be Methanole a type of provender coloringing.A food coloring is any substance that is added to food or drink to change its color. intellectual nourishment coloring is used both(prenominal) in commercial food production 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 water with the use of spectrophotometer. A spectrophotometer is a device 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 different types of spectrophotometers for different purposes. A spectrophotometer uses a light and a prism to bounce light dispatch the sample.
III. Research Question: How is diffusions affected by different aqueous environments?
IV. Hypothesis:
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 first set up the different solutions and then begin recording the data in the provided data table. This experiment will have two parts. In part one you will...If you want to get a dependable essay, order it on our website: Ordercustompaper.com
