Concentration of a Solution (Beer's Law)
{"Image DocumentName": "Concentration of a Solution (Beer\u2019s Law)", "Image ImageDescription": "...Background. Since the colorimeter has a fixed path length b, and the experiment only uses copper(II) sulfate (\u03b5) Beer s law (A = \u03b5 \u00d7 b \u00d7 c ) can be simplified to: A = constant \u00d7 c. The direct relationship between absorbance and concentration is mathematically represented by a straight line: Y = mX + b. The mathematical relationship (equation) will be determined by graphing measured absorbencies at known concentrations of copper(II) sulfate and fitting the data to a line (calibration curve). The equation of the linear fit will be used to determine the concentration of an unknown copper(II) sulfate solution. Y = mX + b.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
