QUESTIONS
Concentation (M)
1.
From your graph determine the absorbance of a 0.40 M CUSO4 solution by interpolation.
Interpolahon the groph at 0.40M CusO, concentrahion the value obsovbance
is found to be 0-38 approximately.
From your graph determine the concentration of a solution which has an absorbance of 0.5
by interpolation.
Interpolahing graph at 0.5 absorbance valuc the concentHation comes out
to be o.54 approximately.
2.
3.
What is the relationship between absorbance and concentration?
So the groph is Shaight line, therefore the rela honship between the
absorbance and concenhahion is direct, i.e, arc direcHy propor Honal
to each other.
Identify any outliers on your graph that do not follow the pattern of the other data.
