Answer 2

The nature of Beer-Lambert law is a linear relationship drawn between the concentration and the absorbance of the solution.

Explanation:

• Beer-Lambert law states that concentration and the absorbance of the solution show a linear relationship.

• This graph enables the concentration of the solution to be calculated by measuring the absorbance.
• It relates the absorption of light by a solution

• Here Beer lamberts law is given by the following equation-           A = εbc, where ε is the molar absorptivity of the absorbing species, b is the path length, and c is the concentration of the absorbing species.
• Absorbance is the reverse of transmittance and it states how much the light the sample absorbs.

• It is also referred to as “optical density.” "Absorbance is calculated as a logarithmic function of T: $A = log10 (1/T) = log10 (Io/I).$"
• Here the deviation in absorptivity coefficient at high concentrations will be due to electrostatic interactions between the molecules and the scattering of light will be due to the particulates in the samples.
