Lab Report #10 Experiment: Beer’s Law Prepared by: Marat Seitimov Section: 538 Date perfomed: 02/18/08 Lab Partner: Kevin, Jonathan Summary: In this experiment we need to find the absorbance of light by different substances of different color. The equipment we used in this experiment is specifically designed so that we can get a very clear look at what is happening. We have a light source and light sensor. We used small laser diodes as the source of light. Laser light is different from ordinary bulb. It is highly directional: it emits a beam of light in a particular direction. Light sensor we used is a silicon photodiode. It measures the amount of light emitted by laser through various solutions. Both laser and sensor are connected to the computer. So we know the amount of light being transmitted by the solution under different conditions. From these results we obtain how much was absorbed. In part A we took five plastic cuvettes and filled them with a .03 M Copper sulfate solution, and placed them between the laser and sensor, in the path of beam. First we put one cuvette, and recorded results. Then started adding cuvettes, and recording results.
