Question

which solution is a homogeneous mixture?
○ sand and water
○ salt and water
○ salad dressing
○ soil

Explanation:

A homogeneous mixture has a uniform composition throughout. Salt (solute) dissolves in water (solvent) to form a solution where the salt particles are evenly distributed, so salt and water is homogeneous. Sand and water is heterogeneous (sand settles), salad dressing is heterogeneous (components separate), and soil is heterogeneous (contains various particles unevenly distributed).

Answer:

B. salt and water
