Experiment 14:Determination of the Cause of a ‘‘Fish-Kill’’ Ashley JoMcCayla TurnbowCHEM 1215 - 01720 October 2015
IntroductionIn this experiment, we will be analyzing a simulated water sample from the Columbia River’s Clark Fork located in Montana. The objective of this experiment is to determine the possible ions that induced a massive fish-kill that took place in 1984. To proceed with this experiment we will be using expertise gathered through prior lab experiences to survey the simulated water sample. This experiment is being performed in order to determine the cause of the fish-kills. For environmental causes this experiment has importance deriving the effects and continued existence on all forms of life surrounding the Clark Fork of the Columbia River. Knowing that the water is ingested by thefish and that it is accessible to all, it suggests that there is a quality problem with the water supply. It is preconceived that high concentrations of heavy metals present in water may lead to fish-kills and this in turn to could promote stricter regulations pertaining to waste management and environment preservation.To determine the heavy metal ion we will be using Emission Spectrum Analysis. In the Emission Spectrum Analysis experiment the tested metal ions will be energized, from the flame of the bunsen burner, and will move to a higher energy state. As the electrons of the the tested ions fall back to their ground state it will produce wavelengths-each ion produces varying wavelengths-which are measured andrecorded by a spectrometer. Using the results received from the spectrometer we can then plot the
