Product description
- Using the data below, calculate the specific and molar extinction coefficients of the product of the photometric reaction in the solution in terms of the substance being determined. Do the desired values change if the wavelength of light, the concentration of the substance (within the concentration range for which the fundamental law of light absorption is satisfied), and the thickness of the absorbing layer are changed?
Determined substance Reagent Reaction product λ, Concentration of substance l, A
Cu2 NH3 H2O Cu(NH3)42 - 620 0.04 g/l 5.00 0.365
