Spectrophotometry was used in the lab to determine whether non-magnetized zeolite‚ magnetized zeolite‚ or charcoal was the more effective sequestration agent for Procion Red Dye. A calibration curve was created with the known concentrations and the absorbances of the Procion Red Dye dilutions at λmax. The slope of the calibration curve was used to determine the concentration of the analytes. As a result‚ charcoal was shown to be the more effective sequestration agent.

First hand investigation of the Dissolution of Solutes Background Information Molar heat of solution * The molar heat of solution of a substance is the heat absorbed when one mole of the substance dissolves in a large excess of water. It is expressed in kJ/mol. * The specific heat of water is a constant‚ with a value of 4.18 J/ g*oC. AIM: To determine the molar heat of solution for two different solids Equipment: * A calorimeter (made using 2 Styrofoam cups with a cardboard lid)

was: If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral

determine the protein concentration of the solution from the standard curve by diluting the solution. Dilution itself is a process of lessening a solute’s concentration in a solution. In this experiment‚ dilution can be done by reducing the amount of protein solution from 1.0 ml to 0.2 ml. Without the process of dilution‚ the absorbance will end up being an extrapolated value causing the result to be unreliable. Part 2 6.

solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We tied off one end of the dialysis tubing to create a bag‚ filled it with distilled water‚ and tie of other end

typically founded on a coherent theory of value creation. All too often companies get into trouble when the stakeholders lose sight of the relevant theory‚ specifically related to value creation. The history of Cicret‚ OMsignal and Ringly‚ Inc provides case in point. The founders of these ventures have a very clear theory about how their company should create value‚ hence this essay is focused on the theme of value creation by the fashion creator and designers of EFSW companies.
