- When measuring iron in river water by spectrophotometry using the ferrozine reaction that is described in the class notes, a student finds that they cannot distinguish their samples from noise (i.e. they are below the limit of detection) when they use a 1-cm cuvette. The student makes the decision to use a 5-cm cuvette in their method instead. a) By how much should the student expect their sample measurements to increase by? Why? b) Will their reagent blank also increase by the same amount? Why or why not? 3.Microsoft Teams Q Search ... 25 Assignment on matching phrases on classification_ units.docx Close Activity File Home Insert Layout References Review View Help O Tell me what you want to do 'Editing v O Comments A Catch up Chat Calibri (Body) v 11 A В I U Av A A Styles v O Find v Reuse Files O Dictate v E Editor : Designer ... ...
