Rate of Diffusion of Saffranin Red Methylene Blue Dye in four physical conditions
Group Members Veronyca Washington Ashley Burnette Valerie Frazier
Objective The purpose of our experiment is to learn the effect temperature has on the diffusion of suffranin and methylene dye. This can be helpful in understanding how diffusion in water occurs in different physical conditions.
Materials 150 mL of hot tap, cold tap, ice, and boiling water Thermometer Stop watch Cups
Procedure A drop of Saffranin red and Methylene blue dye was dropped into each type of water. The time was recorded for the dye to diffuse in the waters. (The cups were not touched once the dye was in the water.)

Conclusion The Methylene Blue and Saffranin Red dyes worked almost equally. The ice water took the longest for both dyes to formulate in. The tap (regular) water took the second longest for both dyes. The hot tap water took the third longest for both dyes. The boiling water took the shortest amount of time because both dyes could easily diffuse throughout the water in heat.
