Calibration Curve for Unknown Concentration by muhammadwasayshahid1 is a document available to read on EtoBox.
The experiment aims to determine the concentration of an unknown solution using a calibration curve that relates concentration to absorbance measured by a UV-Visible spectrophotometer. Standard solutions are prepared, their absorbances are measured, and a calibration curve is plotted, resulting in the equation A = 0.0499C + 0.003. Using this equation, the concentration of an unknown sample with an absorbance of 0.260 is calculated to be approximately 5.15 µg/mL.
