Materials needed: 30-35 mL atrazine stock solution, UV cuvets with caps, UV/Vis spectrophotometer, distilled water, two 25 mL burets, ring stand with buret clamp, beakers, kimwipes

1. Obtain 30-35 mL of atrazine stock solution. For this part of the experiment you will only be allowed 20 mL of atrazine solution, so plan accordingly!

2. Transfer stock atrazine solution to a cuvet and measure its absorbance. Use this value to come up with a plan for a set of dilutions
