In this lab a thionin-iron solution is prepared. Exposing the solution to light energy causes the colored thionin to be reduced by iron (II) ions, resulting in a clear solution. When half of the solution, in a single container, is exposed to light it will turn clear while the half not exposed to light will remain colored.
