SPE: Spectrophotometric Determination of Copper

Part C: Preparation of Beer's Law Plot

*Plot Absorbance vs. Molar Concentration using Excel.  Make sure your graph has all the required features.  Draw the best-fit line, and include the linear equation on the graph. 

 

Part D: Determination of an Unknown Copper Solution Concentration

(Use your linear equation from part C to calculate the concentration of the unknown copper solution.)

Absorbance of unknown copper solution:______________________

Unknown number:  _________
