Problem
A student draws two 5.0 mL samples—one from the top and one from the bottom—of a 250 mL beaker containing an aqueous sodium chloride mixture. Conductivity measurements show both samples have identical molar concentrations of NaCl to two significant figures.
Based on these data, determine whether the mixture in the beaker is homogeneous or heterogeneous and briefly explain your reasoning.
