Transcript of Light Transmittance of Different Dilutions of Gatorade

Light Transmittance of Different Dilutions of Gatorade and Cu(NO3)2
Prelab Activity
In the prelab, we explored light transmittance and got familiar with it for when we had to do the real experiment. We used water to calibrate, and used blue die to experiment with.
Analysis/Conclusion
Post-lab Assessment
Data Table- Transmittance and concentration of copper nitrate
Absorbance vs Concentration of Gatorade
Data Table- Transmittance and concentration of gatorade
Mass percent of copper in Brass
To go even further, we did another experiment to determine mass percent of copper in brass by doing different dilutions of copper nitrate and comparing that to brass. We found light absorbance and molar concentration to do all this.
