Answer:
1.38 M is the concentration of blue solution.
Explanation:
The equation of calibration curve:
[tex]A=\epsilon \times l\times c[/tex]
where,
A = absorbance of solution
C = concentration of solution
l = path length
[tex]\epsilon[/tex] = molar absorptivity coefficient
The graph between A and c will straight line with slope equal to prduct of [tex]\epsilon and l[/tex].
y = 0.194 x + 0.025.
A = 0.194 c+ 0.025
Given the absorbance of solution :
A = 0.293
So, concentration at this value of absorbance will be= c
[tex]0.293=0.194 c+0.025[/tex]
[tex]c=\frac{0.293-0.025}{0.194}=1.381\approx 1.38[/tex]
1.38 M is the concentration of blue solution.
1.38 M is the concentration of blue solution.
Beer-Lambert's law:
The equation for Beer-Lambert's law is:
[tex]A=E*l*c[/tex]
where,
A = absorbance of solution
c = concentration of solution
l = path length
E = molar absorptivity coefficient
The graph between A and c will straight line with slope equal to product of E and l.
y = 0.194 x + 0.025
A = 0.194 c + 0.025
Given:
A = 0.293
So, concentration at this value of absorbance will be= c
[tex]A = 0.194 c + 0.025\\\\0.293=0.194c+0.025\\\\c=\frac{0.0293-0.025}{0.194}\\\\ c=1.38[/tex]
1.38 M is the concentration of blue solution.
