Answer:
For the control experiment: of aqueous solution of erioglaucine has absorbance of
From Lambert-Beer's law we know:
Here; e is the molar absorptivity coefficient of erioglaucine
l = length of cuvette in which the solution is taken =
A sorbance by the erioglaucine = total absorbance - absorbance by distilled
So; by putting the values in the above equation; we get:
So;
The molar absorptivity coefficient of erioglaucine is
The absorbance of erioglaucine in distilled water (contaminated with metal ions) is:
The absorbance of distilled water is
So; absorbance of erioglaucine itself is :
Again using Lambert Beer law; we get:
c = 0.198/5.65 M = 0.035 M
The concentration of the erioglaucine is
