Rate of diffusion of mythelin blue in agar jelly

For this experiment, acetone was placed in a capillary tube and was allowed to diffuse into non-diffusing air that was passed over the test tube at the temperature of 50oC. Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream

Formulate a hypothesis about the rates of diffusion of methylene blue and pottassium permanganate Formulate a hypothesis about the rates of diffusion of methylene blue and pottassium permanganate through the agar gel.

Obtain a petri dish containing agar gel, a piece of millimeter-ruled graph paper, a wax marking pencil, dropper bottles of methylene blue and potassium permanganate, and medicine dropper. Using the wax marking pencil, draw a line on the bottom of the petri dish dividing it into two sections.

Place the petri dish on the ruled graph paper.

Rate of diffusion of mythelin blue in agar jelly

To do this, squeeze the bulb of the medicine dropper, and push it down into the agar. Release the bulb as you slowly pull the dropper vertically out of the agar. This should remove an agar plug, leaving a well in the agar.

Carefully fill one well with the methylene blue solution and the other well with the potassium permanganate solution. At minute intervals, measure the distance the dye has diffused from each well by measuring the radius of the dye.

Continue these observations for 1 hour, and record the results.

[BINGSNIPMIX-3

Which dye diffused more rapidly? Why did the dye molecules move? Compute the rate of diffusion of the potassium permanganate molecules in millimeters per minute as well as the rate of methylene blue.

Prepare the lab report together with your introductions, hypothesis, discussions, results, conclussions, and then the references. Please state the details of all the questions that I am asking. High MW substances diffuse slowly with smaller diameters and small MW substances diffuse quickly with higher diameters.

Since, the polymerization ofblue to colourless. Fig.1 You can see how far the Graph 2 – The effect of SA:V on the rate of diffusion of ascorbic acid into agar/DCPIP blocks R² = Investigating The Effect of SA:V On The Rate Of Diffusion. Aim To measure how different concentrations of mythelin blue affects the rate of diffusion through agar jelly.

Hypothesis The diffusion of mythelin blue is directly proportional to its concentration, hence as the concentration increases; the rate of diffusion increases too. Aim To measure how different concentrations of mythelin blue affects the rate of diffusion through agar jelly.
