Question

A 0:005 M aqueous solution of a certain substance absorbs 15% of the incident light in a Lambert-Beer law cell
of path length 2 cm. Calculate the concentration required for 90% absorption of the incident light.

Answer 1

Answer:

The absorbance has a logarithmic relationship to the transmittance; with an absorbance of 0 corresponding to a transmittance of 100% and an absorbance of 1 corresponding to 10% transmittance.
