Beer's law and spectrophotometry Flashcards
1
Q
Spectrophotometry
A
a method of measuring how much light a substance absorbs. You measure this be testing the intensity of the light beam as it passes through the sample solution
2
Q
Beer’s Law:
A
the amount of light absorbed is portional to the concentration of the solution
not valid at high solution concentrations
3
Q
Beer’s law formula
A
Absorbance= molar absorpivity x length of light path x concentration
