Case Solution Essay

states that the size of a particle will not change the water potential or occurrence of osmosis in a solution-submerged cell, only the amount of the solute in the solution will affect osmosis. To test this, we used three different sized solutes—sucrose, glucose, and NaCl—to see if the size of the solute had an effect on the osmosis of water into or out of white potato cells that were submerged in solutions containing the 3 solutes. We found that the size of the particles of solute does not affect osmosis

rate of osmotic pressure between tap water and surcose solutions. This will happen by using different concentrations of sucrose (20%, 40%, 60%) afterwards, the change in mass ratio would be observed over time. Other factors affect the rate of osmosis, factors like, pH, Temperature and also pressure. Hypothesis: With predictions, the dialysis bag acting as a semi-permeable membrane in the prescence of sucrose solution, where the water potential is high would cause the mass

Creating Solutions of Standard Molarity Krishnaben Patel Katherine Asibal CHEM 1251L-027 10-1-2014 Introduction: In this experiment, a series of 〖Cu〗^(2+) solutions of different concentrations were prepared using the dilution technique. The principles of spectroscopy of and appropriate usage of Spec 20 was taught. The spectrophotometer instrument was used to measure the amount of light that passes through a solution. Beer-Lambert law was applied to determine the concentration of 〖Cu〗^(2+) in an unknown

lecture, you will be able to Define viscosity and viscosity coefficient Outline the method to measure viscosity using Ostwald viscometer Determine the average molecular weight of a polymer Determine the surface concentration of 1-butanol in aqueous solution Measure the distribution coefficient of a solute betweenn two solvents 39.1 Introduction Viscosity, one of the transport properties, arises because of intermolecular attractive and relatively long-range forces. Viscosity coefficient ([pic])

blood cell lysis and its absorbance values, as well as its overall histology. In table 1, different solutions are used to test for the occurrence of red blood cell lysis and furthermore, their absorbance values. Although the values for table 1 were very scattered and varied greatly, it can be concluded that solutions of 5% and 2% NaCl had higher absorbance values at 640 nm, while the rest of the solutions read higher in the spectrometer at a reading of 540 nm. It appears as though the stronger the percentage

In this experiment, the concentration of an unknown permanganate solution will be determined. Spectroscopic techniques will be used to measure various known concentrations of permanganate solutions to create a calibration curve for the absorbance of light vs. the concentration and will be used to determine the unknown concentration1. Introduction In order to perform this experiment, proficiency with using spectrometers, burettes, volumetric flasks, weighing by difference, and making a hot-water bath

the egg in a solution and determine if that solution is isotonic, hypertonic, or hypotonic in relation to the egg. A solution is a “mixture of two or more substances in which the molecules of the substances are evenly distributed” (Miller/Levine 2000). The substances in a solution are solutes, “the substance that is dissolved” (Miller/Levine 2000), and solvents, “the substance in which the solute dissolves” (Miller/Levine 2000). In this case, the egg will be put in a salt-water solution, where salt

Danis Heto Have you ever wondered that if you put ice into a drink, the substances in the drink will make it melt faster. This is exactly the case, I will be seeing how the substances that we use in our everyday life affect the melting point of ice. I will be looking at what causes the freezing point depression, how substances affect the freezing point of ice, and the purposes of changing the freezing point of ice. The melting point of ice is the given temperature that a substance will melt, and
