Question

which is an example of a homogeneous mixture that is a solution?
a salad dressing
b salt water
c gelatin
d salt and pepper

Explanation:

To determine the answer, we analyze each option:

• Option a (salad dressing): It is a heterogeneous mixture (components separate, e.g., oil and vinegar layers).
• Option b (salt water): Salt (solute) dissolves in water (solvent) uniformly, forming a homogeneous mixture (solution) as the composition is consistent throughout.
• Option c (gelatin): It is a colloid (a type of heterogeneous mixture with dispersed particles, not a true solution).
• Option d (salt and pepper): A heterogeneous mixture with visible separate particles.

Answer:

b. salt water
