Question
Chapter 13, Problem 13.21QAP
Interpretation Introduction
Interpretation:
The differences between a monochromator, a spectograph, and a spectrophotometer should be determined.
Concept introduction:
A monochromator is a device that is basically used as a wavelength selector for the monochromatic light incident on it. A spectrograph is a device that separates the wave into all of its incoming wavelengths. Whereas a spectrophotometer is a device that is used to measure the properties like transmittance and the absorbance of the solution.

- What are the advantages and disadvantages of decreasing monochromator slit width?arrow_forwardMany ions form colored solutions when dissolved in water. For example, aqueous Cu2+ solutions are light blue and aqueous Ni2+ solutions look light green. These metals in particularare often found in stainless steel. Would you expect their presence in your samples to interfere in the spectrophotometric analysis of permanganate at 525 nm? Why or why not? I think the answer is that I would expect the Cu2+ in my samples to interfere but not Ni2+ because the Ni2+ is green, signifying a higher wave length that the spectrometer wouldn't be able to pick up on because it was only set to 525 (blue-ish) where as the green is 530-ish.

To evaluate a spectrophotometer’s accuracy by measuring absorbance, a solution of 60.06 mg/L K2Cr2O7 in 0.0050M H2SO4 was carefully prepared together with a 0.0050 M H2SO4 as a reagent blank. If the spectrometer’s signal is properly calibrated, it has been reported that this solution should provide an absorbance of 0.640 +- 0.010 at wavelength 350 nm.
