Question

Which of the following expressions is incorrect?
a. A = log(%T)
O b. A = -log(1/o)
O C. A = Elc + constant
O d. A = Elc
e. A = -log(96T/100)

Expert Solution

Theory

$The lambert - Beer' s law of absorption is A = εcL and A = \log (\frac{I_{0}}{I}) Where, A = Absorbance ε = Molar extinction coefficient c = concentration of solution L = width of cuvette I_{0} = Intensity of light before absorbance I = Intensity of light after absorbance$

$Transmittance, T = \frac{I}{I_{0}} % T = \frac{I}{I_{0}} \times 100$
