Final answer:
Bronze is not a solution; it is an alloy, which is a solid mixture. Soda, homogenized milk, and sea water qualify as solutions or colloids, not bronze.
Step-by-step explanation:
The substance that is NOT a solution among the given options is bronze. To clarify the concepts:
- Soda is a homogeneous mixture of carbonated water, sugar, and other substances, making it a solution.
- Homogenized milk is a colloid, which means that the fat particles are dispersed evenly throughout the liquid but are too large to be considered a true solution.
- Bronze is an alloy of copper and tin and is a solid mixture, not a solution.
- Sea water is a homogeneous mixture of salt and water and other minerals, which qualifies it as a solution.
Therefore, all of the substances listed except bronze are considered solutions.
