Homework Help: chemistry

Posted by kkk on Tuesday, January 5, 2010 at 5:59am.

why do you need to construct a calibration curve when doing spectrophotometric determinations? Is it not possible to obtain the concentration of the unknown solution by simply getting the extinction coefficient of the species under study and then determine its concentration in the unknown solution by using Beer's law? Thanks!
