Problem
A student measures the absorbance (proportional to CuSO4 concentration) of solutions X and Y at three depths in identical beakers.
Depth Solution X Solution Y
Surface 0.42 0.15
Mid-depth 0.43 0.38
Bottom 0.41 0.69
Which inference is most consistent with the data?
(a) Both solutions are homogeneous.
(b) Solution X is heterogeneous and Solution Y is homogeneous.
(c) Both solutions are heterogeneous.
(d) Solution X is homogeneous and Solution Y is heterogeneous.
