Most iron(III) compounds are very weakly colored, and do not lend themselves well to visible spectrometric analysis. Suggest a way in which their analyzability can be improved.
Explain the group point, color and magnetic properties before and after oxygen binding.
You wish to measure the iron content of the well water on the new property you are about to buy. You prepare a reference standard Fe3+ solution with a concentration of 5.74×10−4 M. You treat 14.0 mL of this reference with HNO3 and excess KSCN to form a red complex and dilute the reference to 60.0 mL. The diluted reference is placed in a cell with a 1.00‑cm light path. You then take 30.0 mL of the well water, treat with HNO3 and excess KSCN, and dilute to 100.0 mL. This diluted sample is placed in a variable pathlength cell. The absorbance of the reference and the sample solutions match when the pathlength is 1.76 cm. What is the concentration of iron in the well water? For each solution, the zero is set with a blank.
To establish a standard curve for a Big standard curve using Bluret, the spectrophotometer wavelength is set on which value? the wavelength at which the copper(Il) complex's absorption value is the lowest A Big standard curve should not be drawn up using the Buiret method the wavelength at which the copper(II) complex's absorption value is the highest the wavelength at which the Big-Bluret complex's absorption value is the highest the wavelength at which the Big-Biuret complex's absorption value is the lowest O O C
A series of standard iron-phenanthroline [Fe(phen)3]2+ complex ion solutions were prepared. The absorbance of each solution was measured at a wavelength of 510 mm. A calibration curve of absorbance vs. concentration was then plotted to obtain a linear equation of y = 0.0018x+0.0749. The absorbance of an unknown [Felphenly solution was measured to be 0.326. Calculate the concentration of the complex ion. NOTE! Report your answer as a WHOLE #. Type your answer...
