1. 1.

   A student analyzes three liquid mixtures in identical glass cuvettes: Liquid 1 passes completely through standard filter paper without leaving residue and shows no luminous beam when illuminated by a laser; Liquid 2 passes through the filter paper without leaving residue but clearly scatters the laser beam along its path; and Liquid 3 leaves a solid residue on the filter paper, yielding a clear filtrate. Based on these experimental observations, which statement correctly classifies these mixtures?

   • A) Liquid 1 is a homogeneous mixture, whereas Liquid 2 and Liquid 3 are heterogeneous mixtures.
   • B) Liquid 1 and Liquid 2 are both homogeneous mixtures because neither leaves a residue on standard filter paper.
   • C) Liquid 2 is a homogeneous mixture because its components remain completely dispersed without settling, while Liquid 1 and Liquid 3 are heterogeneous.
   • D) All three liquids are heterogeneous mixtures because any liquid containing multiple components possesses microscopic phase boundaries.
