Question
Chapter 14, Problem 14.16QAP
Interpretation Introduction
(a)
Interpretation:
The formula of the complex should be determined.
Concept introduction:
In photometric titration, absorbance of the solution is measured to determine the endpoint of the titration. This is based on the theory that the absorbance of a solution is directly proportional to the concentration of analyte. A graph is plotted between absorbance versus volume of titrant added.
Interpretation Introduction
(b)
Interpretation:
The molar absorptivity of the complex should be determined.
Concept introduction:
The Beer-Lambert Law is:
where,
A − absorbance
l − length of the solution light passes through (cm)
c − concentration of solution (mol/L)
