Correlation Between Methylene Blue And Potassium Permanganate

All things, living or nonliving, consist of atoms and molecules. These particles are constantly in motion, and this continuous motion allows for the disbursement of molecules, or diffusion. The overall net movement of these molecules will go from areas of higher concentration, to areas of lower concentration. Therefore, following a concentration gradient (Martini). The rate of diffusion of these molecules, in accordance with Fick’s law of diffusion, is directly proportional to the concentration gradient present. However, the concentration gradient is not static and will change over time and with distance, therefore changing the rate of diffusion. It is hypothesized that the two solutions being tested, Methylene Blue and Potassium Permanganate, will begin their initial diffusion in the agar gel at a quick rate, and then progressively regress over the allotted time of 1 hour. Another factors other that will have an effect on rate of diffusion is molecular size. There is a substantial difference in molecular weight between Methylene Blue (320 g/mol) and Potassium Permanganate (158 g/mol). The combined molecules present in Potassium Permanganate are lighter than those in Methylene Blue, and therefore should allow it to diffuse more rapidly.

Activity 3: Investigating Osmosis and Diffusion Through Nonliving Membranes. In this activity, through the use of dialysis sacs and varying concentrations of solutions, the movement of water and solutes will be observed through a semipermeable membrane. The gradients at which the solutes NaCl and glucose diffuse is unproportional to any other molecule, therefore they will proceed down their own gradients. However, the same is not true for water, whose concentration gradient is affected by solute ...

...epending on the patient’s dehydration, therefore also affecting the patient’s tonicity. The patient would also be losing water insensibly, in an unperceived way through their skin and lungs (Martini). This could be combative with the patient experiencing shortness of breath, in order to preserve some water from evaporating. In order to maintain proper osmolarity, the intercellular fluid would loose water to the extracellular fluid. This patient would need the replace the fluids he has lost by drinking water, or through intravenous isotonic crystalloid. I would suggest intravenous isotonic crystalloid since it would restore the body to homeostasis much quicker than through drinking. It is important that fluid balance, membrane transport, and overall homeostasis be maintained, for the longer the body is out of homeostatic range, the more detrimental the effects will be.
