Final answer:
Beer's Law is a principle in chemistry that relates the absorbance of light by a substance to its concentration in a solution. Several conditions must be met for Beer's Law to apply, including a linear relationship between concentration and absorbance, absence of interfering substances, and a specific wavelength of incident light.
Step-by-step explanation:
Beer's Law, also known as the Beer-Lambert Law, is a principle in chemistry that relates the absorbance of light by a substance to its concentration in a solution. For Beer's Law to apply, several conditions must be met:
- The substance being measured must have a linear relationship between its concentration and its absorbance.
- The solution must be free of interfering substances that might affect the absorbance of the substance being measured.
- The incident light must have a specific wavelength that is not absorbed by any other substances in the solution.
These conditions ensure that accurate measurements can be made using Beer's Law.
