A student measures the absorbance of a solution containing FeSCN2 ion using a spectrophotometer. The cuvette used by the student has two frosted walls and two transparent walls. The student properly orients the cuvette so that the path of the light goes through the transparent sides of the cuvette when calibrating the spectrophotometer. How will the measured absorbance of the FeSCN2 be affected if the student incorrectly orients the cuvette so that the path of the light is through the frosted sides of the cuvette

If the student incorrectly orients the cuvette so that the path of the light is through the frosted sides of the cuvette, the measured absorbance of the FeSCN solution will be higher than the actual absorbance.

The question is incomplete, the complete question is;

A student measures the absorbance of a solution containing  FeSCN on using a spectrophotometer. The cuvette used by the student has two frosted walls and two transparent walls. The student properly orients the cuvette so that the path of the light goes through the transparent sides of the cuvette when calibrating the spectrophotometer. How will the measured absorbance of the FeSCN be affected if the student incorrectly orients the cuvette so that the path of the light is through the frosted sides of the cuvette?

A) The measured absorbance of the FeSCNsolution will not be affected

B) The measured absorbance of the FeSCN solution will be higher than the actual absorbance

C) The measured absorbance of the  FeSCNsolution will be lower than the actual absorbance.

D) The effect on the measured absorbance of the  FeSCN solution depends on the concentration of the FeSCN solution

A spectrophotometer is an instrument used to measure the concentration of a solution by means of the absorbance according to Beer-Lambert's law. The absorbance of recorded by the detector reflects the concentration of the analyte specie in the solution.

If the cuvette is wrongly oriented such that light is scattered by the frosted cuvette, a higher absorbance is recorded by the detector hence  the measured absorbance of the FeSCN solution will be higher than the actual absorbance.

Spectrophotometer is a laboratory instrument, in which concentration of a solution is measured by the absorbance or emittance of the solution. If the student incorrectly orients the cuvette to the frosted site, such that the measured absorbance of the FeSCN solution will be higher.

Spectrophotometer is the instrument in which the absorbance of a solution is based on the Beer-Lambert's law. The detector records the absorbance of a solution and reflects the concentration of analyte species in the solution.

The student if wrongly orients cuvette then:

Therefore, if the cuvette is wrongly oriented such that the light scattered by frosted cuvette will be higher than the measured absorbance.

ill try to . no promises tho.

explanation:

so what is the problem with your lab report and whats the subject of the lab report? i will you
