  • The Effect Of Molecular Concentration On The Rate Of Diffusion

    700 Words  | 3 Pages

    INTRODUCTION Diffusion takes place on molecules of liquid, gas or a solution. It is the movement of molecules from an area of higher concentration to an area of lower concentration down a concentration gradient in random motion (D G McKean, Dave Hayward 2014). The diffusion of molecules passing across a lipid bilayer is also affected by its “hydrophobicity”. Diffusion can be done without the use of energy due to the randomness of the movements of particles. Molecules move from areas where they are

  • Grape Juice Concentration Lab Report

    967 Words  | 4 Pages

    In conclusion, when the concentration of grape juice increased, the average percentage change in the mass of the potato cylinders decreased. The increased concentration of grape juice means that there are more glucose molecules and, hence, the solution had a lower water concentration. There were more water molecules in the potatoes, thus diffusing into the water, against the concentration gradient in order to reach equilibrium. The water being lost decreased the mass of the potato cylinders. For

  • Critical Micelle Concentration Lab Report

    1074 Words  | 5 Pages

    Critical Micelle Concentration The CMC (Critical Micelle Concentration) is the amount of a surfactant molecule in a bulk stage, beyond which aggregates of surface active agents, so-called micelles. The CMC is a significant distinctive property of surfactants for its application. Generally molecules have two different constituents with differing attraction for the solutes. The component of the molecule that has an empathy for polar solutes, like water, is assumed to be hydrophilic. The component of

    Holocaust Reflection: Hierarchy in Concentration Camps When I think of the Holocaust, I think of constant fear, horrible genocide of innocent people, and terrible living conditions. For twelve years, people were imprisoned for their faith, political views, or where their love lied. When learning about the terrible tragedy in middle school, I was under the impression that every person held prisoner in the concentration camps was treated the same, inhumane way. However, that assumption is completely

  • Concentration Of H2O2 In Yeast

    706 Words  | 3 Pages

    4.3: EXPERIMENTAL PROCEDURE A standard solution of H2O2 was prepared with a concentration of 0.1000 ± 0.0015 mol dm-3 by diluting a 0.88 mol dm-3 sample of H2O2 in an Erlenmeyer flask. Instantly, the Erlenmeyer flask was secured with a rubber stopper to limit the risk of H2O2 from decomposing quickly. Since the reaction of the decomposition of H2O2 with the catalase found in yeast is very fast, a low concentration of H2O2 was kept constant at 0.1000 ± 0.0015 mol dm-3 in order for the reaction
