"Case solution" Essays and Research Papers

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

The process of osmosis doesn’t stop till both solutions are equal in and out of the cell membrane. Osmotic pressure is needed to stop the process of osmosis. “The rate in which osmosis occurs depends on the temperature of the solution‚ the concentration of the solute‚ and the electrical charge of the solute.” Osmosis occurs in the large and small intestines.
