Pre-lab: Experiment 1. Photochemical Reaction with Ferrioxalate
Concepts and Techniques to Review:
•Use of a spectrophotometer
Introduction: This experiment involves the combination of ferric nitrate and oxalic acid to form a
ferrioxalate which undergoes a photochemical reaction when it is introduced to light which
produces ferrous ions. A second solution of potassium ferricyanide is then prepared and added
to the ferrioxalate solution. The substance will be tested using different colours and exposure
times, the ferrioxalate will then be examined by spectrophotometery to discover what colours of
light it absorbs.
Purpose: In this experiment we will examine the properties of photosensitive solutions such as
sensitivity to light as well as heat.
