Spectroscopy measurements may be made in either percent transmittance (%T) or absorbance (A). Based on the mathematical relationship between absorbance and transmittance, A = -log(%T), explain why calibration curves of absorbance versus concentration may deviate from a straight line when A < 0.1 and when A > 1. Think about the detection limits of the colorimeter!
