Title: Determining Concentration
Post by: rj1027 on December 11, 2004, 09:47:34 PM
using spec techniques, determine the concentrastion of NF in solution.
I feel that U.V. Spec is the answer using Beer's Law. where A=CEL.
Some people want to argue this answer saying that IR will tell you the Concentration. I disagree b/c IR tells fuinctional groups not concentration.
Is this correct?

yeah, Beer-Lambert's law is suitable for concentration determination but IR's mainly use is determining the functional group....A spectrophotometer could be used for determining concentration if a calibration curve is available.
