What is UV-VIS Spectroscopy of Potassium Dichromate about?

This experiment aimed to determine the concentration of an unknown potassium dichromate solution using UV-VIS absorption spectroscopy. Standard solutions of known concentrations were prepared and their absorbances measured. A calibration curve of absorbance versus concentration was prepared, showing a linear relationship. The curve equation and R^2 value indicated a good linear fit. The absorbance of an unknown solution was then measured and its concentration determined using the calibration curve.
