(a)
Interpretation:
The formula of the complex should be determined.
Concept introduction:
Slope-ratio method is used for weak complexes,
When L is in excess,
When M is in excess,
Therefore slope of the plot of absorbance versus concentration of M or L gives
The ratio of the two slope will give the combining ratio of M and L.
(b)
Interpretation:
The molar absorptivity of the complex and its uncertainty should be determined.

- Mixing the chelating reagent B with Ni(II) forms the highly colored NiB22+, whose solutions obey Beer’s lawat 395 nm overa wide range. Provided the analytical concentration of the chelating reagent exceeds that of Ni(II) by a factor of 5 (or more), the cation exists, within the limits of observation, entirely in the form of the complex. Use the accompanying data to evaluate the formation constant Kf for the process Ni2++2BNiB22+arrow_forwardThe absorbance values observed during the determination of the complex stoichiometry with the Job method using the spectroscopic method were plotted and the following correct equations were obtained.

The mercury(II) in a soil sample was extracted into an organic solvent containing an excess of TTC , and the resulting solution was diluted to 100.0 mL in a volumetric flask. Five-milliliter aliquots of the analyte solution were then transferred to six 25-mL volumetric flasks. A standard solution was then prepared that was 5*10^-6 M in .
