Question

Why is it important to measure absorbance at max?

Answer 1

Answer:

There are two reasons that it is important to measure the absorbance of a substance at the wavelength of maximum absorbance max). ... Compounds absorb light differently at different wavelengths, and they will be most concentrated at Lambda-max.

Answer 2

Heya mate..........

The higher the absorbance of light by a solution, the lower the percent transmittance. The wavelength at which absorbance is highest is the wavelength to which the solution is most sensitive to concentration changes. This wavelength is called the maximum wavelength or λmax.

Hope this will help you.......
