How to Calculate Concentration Using Beer Lambert Law: Step-by-Step Guide

How to Calculate Concentration Using Beer Lambert Law

fascinated by science of spectrophotometry learn calculate concentration solution using Beer Lambert Law? Look further! Blog post, will delve into of powerful law show apply real-world scenarios.

Beer Lambert Law

The Beer Lambert Law, also known as the Beer-Lambert-Bouguer Law, is a fundamental principle in the field of spectrophotometry. Describes relationship concentration solution amount light absorbs. Law expressed equation:

A = εlc

Where:

  • A absorbance solution
  • ε molar absorptivity (also known molar extinction coefficient)
  • l path length cuvette (in centimeters)
  • c concentration solution (in mol/L)

Calculating Concentration

To calculate the concentration of a solution using the Beer Lambert Law, you can rearrange the equation to solve for c:

c = A / (εl)

Now, let`s take look example see equation applied practice.

Case Study: Determining the Concentration of a Copper(II) Sulfate Solution

Suppose we have a copper(II) sulfate solution with an absorbance of 0.6 at wavelength 600 nm, path length 1 cm. The molar absorptivity of copper(II) sulfate at 600 nm is 0.015 L/(mol·cm). Using the Beer Lambert Law, we can calculate the concentration of the solution as follows:

Absorbance (A) Molar Absorptivity (ε) Path Length (l) Concentration (c)
۰.۶ ۰.۰۱۵ L/(mol·cm) ۱ cm ۰.۶ / (۰.۰۱۵ * ۱) = ۴۰ mol/L

Understanding How to Calculate Concentration Using Beer Lambert Law valuable skill anyone working field analytical chemistry. By mastering this technique, you will be able to accurately determine the concentration of a solution based on its absorbance and molar absorptivity. So, grab your spectrophotometer and start exploring the fascinating world of quantitative analysis!
