This experiment demonstrates the linear relationship between the absorbance and the concentration of a colored solution. . UV-VIS Spectroscopy. Ultraviolet and Visible Absorption Spectroscopy. When matter absorbs electromagnetic radiation in the domain ranging from the near ultraviolet to the very near infrared (180-1100nm) it is considered to be UV/Visible.. concentration. BCH 333 [practical]. Objectives:. 1. What is absorption spectrum and determination of . λmax. .. 2. Standard curve and determination of an unknown . concentration . for a . solution.. The absorbance (A) is proportional to the concentration (c) of the solution and the Calculated on the basis that is 1 cm and c is 1% w/v solution, the absorbance is called specific absorbanc Figure 1.

Spectrophotometry. . . . is . the measurement of light absorption or transmission .. It is an analytical technique that is applied to obtain valuable information , such as the identity of an unknown compound by their characteristic absorption spectra (qualitative analysis ) , and determination of the unknown concentration of an analyte (quantitative analysis ) .. Many compounds of biological importance do not have a distinct absorption maximum . λ. max . . . Nevertheless, their concentration can be determined if they can be linked to or coupled with a reaction that fulfills the following conditions :. copper (II) . sulfate. solution. , whose concentration you know. ..
