Q. B

Problem 1 (LONG QUESTION) A student was tasked to investigate the concentration of a KMnO4(aq ) solution in a 250-mL flask. She prepared a dilute sample of the dye and performed a wavelength scan of the solution. The result of the scan is shown below. (a) Estimate the wavelength at maximum absorption, max. Why is it important to determine the concentration of the colored solution at this wavelength? max=5+5nm Since silght changes in C can mare (b) If the student used the stock solution for getting another wavelength scan, how would the scan be a Agni ficant different from the previous scan
