    will move from an area of high concentration to low concentration. Also‚ the rate of which it would move depending on concentration. The higher the concentration of sucrose inside of the dialysis bag‚ the faster the rate of water will travel into the bag. The rate of osmosis increases as the concentration of sucrose inside the bag is higher. Correspondingly‚ with bag 5‚ the water inside the dialysis bag would travel once again to a place of lower water concentration‚ the sucrose in the beaker. This

    Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule

    The Effect of Concentration on Absorbance Background Information The purpose of the “Determining Solution ‘Concentration’ Using A Spectrophotometer” lab was to use a spectrophotometer to find the relationship of concentration and absorbance obeying the Beer-Lambert law‚ which states concentration and absorbance are directly related‚ to then further determine the concentration of three unknown solutions. With the assumption that the solutions obey the Beer-Lambert law it is predicted that as concentration

    state of equilibrium when its properties do not change at time passes. Equilibrium is a state of a reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by quantitatively defining

    Analysis The trend that my graph and results show is that when the potato was placed in a solution that had a higher concentration than the chip itself‚ the potato lost weight (0.4‚ 0.6‚ 0.8 and 1.0 molars). In the same way when the potato chip was placed in a solution that had a lower concentration than itself‚ the potato chip gained weight (0.0 and 0.2 molars). For my results I calculated the percentage gain/loss in weight using the following formulae: Average change in weight/weight at

    Quantitative analysis – where the quantity of a particular biomolecule in a sample is determined‚ either as an amount (e.g. as g‚ or mol) or in terms of a concentration in the sample (e.g. as g/l‚ or mol/l). For example‚ a blood sample might be analyzed to determine its pH (-log10 [H+])‚ alcohol concentration in mg/mL‚ or glucose concentration in mmol/l. Your choice of approach will be determined by the purpose of the investigation and by the level of accuracy required. Major types of biomolecules
