please solve. If the answer is "no error" and it asks me to type something, and i typed a-helix, its always wrong.
Can you please solve and explain this for me in a simple way? I cant seem to comprehend this problem.
Part I. Problem solving. Include all necessary calculations 13 provide plots and graphs. Complexation wl diphenyl carbazide (OPC) in acidic media is another type of sensitive photometric method used for the analysis of aqueous. hexavalent chromium. At 540nm the cherry-red complex as a result of DPC reaction w/ chromium can be photometrically measured. at this wavelength. - a 25mL The UV-vis analysis for the determination of nexavalent chromium in ground water sample is given below. The experiment was based on external calibration method w/ each measurement sample prepared are as follows lab sample analysis contained the standard 100 ppb croy cor groundwater sample, volumes used as indicated below), 12.50 mL of 0.02 M H2Soy and 5.50 ml of 100 ppm DPC (wi water to adjust final volume to 25-ml). The main stripping method was square wave voltammetry, following the conditions set in the main ASV experiment. Standard 100 Volumetric Groundwater H2SO4 0.20 M, flask Sample, mL ppb CrO4*, 100…
