In the lab, you determined the wavelength whose absorbance was maximum. That wavelength was used to measure the absorption of each of the standard solutions. With these data construct a calibration curve. Remember: 1. Properly identify the axes on the graph. 2. Use a suitable title that includes the wavelength of maximum absorption. 3. Include the equation of the straight line that best fits your values and the coefficient of determination (R2, “R-squared").

Transcribed Image Text:In the lab, you determined the wavelength whose absorbance was maximum. That wavelength
was used to measure the absorption ofeach of the standard solutions. With these data construct a
calibration curve.
Remember:
1. Properly identify the axes on the graph.
2. Use a suitable title that includes the wavelength of maximum absorption.
3. Include the equation of the straight line that best fits your values and the coefficient of
determination (R2, “R-squared").
