- Most iron (III) compounds are very weakly colored, and do not lend themselves well to visible spectrometric analysis. What is one possible reliable way to improve the analysis? Group of answer choices: Find a different way to analyze the sample Use a larger sample Complex the iron with another chemical to increase its absorbance Analyze something elseMost iron (III) compounds are very weakly colored, and do not lend themselves well to visible spectrometric analysis. What is one possible reliable way to improve the analysis? Find a different way to analyze the sample Use a larger sample Complex the iron with another chemical to increase its absorbance Analyze something elseA 50.0 mL sample containing Cd2+ and Mn2+ was treated with 65.1 mL of 0.0400 M EDTA. Titration of the excess unreacted EDTA required 15.0 mL of 0.0190 M Ca2+. The Cd2+ was displaced from EDTA by the addition of an excess of CN−. Titration of the newly freed EDTA required 22.7 mL of 0.0190 M Ca2+. What are the concentrations of Cd2+ and Mn2+in the original solution?

Why? And does it require a standard calibration curve? If not, how can the amount of analyte be determined?What about Polarography?
- A. Consider three possible ways in which Cu2+ could sorb to a hematite surface: (1) outer-sphere sorption, (2) inner-sphere sorption, and (3) precipitation as a Cu(II)-hydroxide. Describe the differences in the coordination environment - i.e. identify of the nearest atomic neighbours and interatomic distance within 0.5 nm (5 Å) of a given Cu(II) ion - of each sorption process. You are welcome to draw a schematic illustration to help clarify your text.Can someone help me with a question. Determine the critical cation to anion ratio (Rx/Rz) that separates cubic coordination (8-fold) from octahedral coordination (6-fold). Use the figures below to guide you through your calculation.Which form if EDTA is used in any analytical experiment? Why?
- A. Cu + Cd2+ -> Cd + Cu2+B. Cd + Cu2+ -> Cu + Cd2+C. Cd + Ni2+ -> Ni + Cd2+The red color of soil is often due to the presence of iron. Metal ions are extracted from soil by stirring the soil in acid and then filtering the solution. One method for the analysis of Fe2+ is to form the highly colored Fe2+–thioglycolic acid complex. The complex absorbs strongly at 535 nm. Calibration standards of 1.00, 2.00, 3.00, 4.00, and 5.00 ppm are prepared by transferring appropriate amounts of a 10.0 ppm working solution of Fe2+ into separate 50-mL volumetric flasks, each of which contains 5 mL of thioglycolic acid, 2 mL of 20% w/v ammonium citrate, and 5 mL of 0.22 M NH3. After diluting to volume and mixing, the absorbances of the standards are measured. a)What is the effect on the reported concentration of iron in the sample if there is a trace impurity of Fe2+in the ammonium citrate?The red color of soil is often due to the presence of iron.

Fit the data to straight line and find the equation for the straight line and the R2 value. (Hint: Think about what to do with the absorbance of the blank.)
