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. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can

to Volume ratio in Agar Introduction: What is an efficient way to maximize mass but minimize diffusion time in cell? Answer: An efficient way to maximize mass but minimize diffusion time in a cell is to increase its surface area. If you increase the surface area of a cell relatively to its volume‚ then the diffusion time will decrease. Materials: Agar cubes‚ bromothymol blue- pH indicator‚ vinegar‚ ruler‚ spatula‚ beaker. Methods: I used agar cubes as cell models. The agar was cut into blocks

method was conducted by placing 2.0641 grams of salicylic acid in a dry 125 mL Erlenmeyer flask. In a fume hood‚ 4 mL of acetic anhydride and 5 drops of concentrated sulfuric acid were added to the flask. The contents were swirled in the flask and then heated for 20 minutes in a hot water bath. After the 20 minutes were up‚ 10 mL of cold water were added in 1 mL increments. The flask was cooled for 10 minutes and occasionally stirred. The crystals that formed were collected via filtration and weighed
