Answer to Question #2026 in Inorganic Chemistry for vinay

Question

State Beer-Lambert law. Explain its application.

Answer 1

The Beer-lambert law stae that the quantity of light absorbed by a substance dissolved in a fully transmitting solvent is directly proportional to the concentration of the substance and the path length of the light through the solution.

$$I=I_oe^{-\mu(x)}$$

Where,

1. $I$ : intensity
2. $I_o$ : initial intensity
3. μ: coefficient of absorption
4. x: depth in metre
   

Applications-

(1) In atmosphere

(2)In analytical chemistry
