Question

what beer's law ?

Accepted Answer

Beer's law, also known as the Beer-Lambert law, describes the relationship between the concentration of a solute in a solution and the amount of light absorbed by the solution.

Beer's law states that the absorbance of a solution is directly proportional to the concentration of the solute.
It is commonly used in spectrophotometry to determine the concentration of a substance in a solution.
The equation for Beer's law is A = εcl, where A is the absorbance, ε is the molar absorptivity, c is the concentration, and l is the path length of the light through the solution.
Beer's law assumes that the solution is dilute and that the absorbing species does not interact with other solutes or the solvent.
It is important to calibrate the spectrophotometer using standard solutions of known concentration to ensure accurate measurements.

Accepted Answer

It satated that absorbance (A) is proportional to the concentration (c) of the solution. It= Io e^-kc
