Question

When solid copper and zinc are mixed to form the metal alloy brass, what kind of mixture results? Homogeneous or heterogeneous And, is the mixture a solid solution, a solid compound, an aqueous solution, or a salt?

Answer 1

Step 1 - Briefly remembering the definition of homogeneous or heterogeneous

Homogeneous mixture ---> one cannot distinguish the components of the mixture. It is a one phase mixture, like water and sugar or water and salt.

Heterogeneous mixture ---> one can visibly distinguish the components of the mixture. It has one or more phases, like water and oil or water and sand

Step 2 - Answering the exercise

When we look at brass, we cannot distinguish the two substances from one another. Therefore, it is a homogeneous mixture. Also it is a solid solution.

Solid solutions are usually found in metal alloys.

Answer: homogeneous substance, solid solution
