Medo da luz

Synopsis: Did you know that you can change the color of a solution just putting them light?
Well, believe it. In this experiment we will demonstrate that this is possible. The reaction performed in this experiment demonstrates that light energy can induce a reversible electron transfer reaction analogous to that which occurs in photosynthesis manner. Due to this reaction occurs, the solution changes color, as we shall see throughout this experiment.
