Why is brass made of copper and zinc called a solid solution?
Answer and explanation
Correct answer: Because both components are uniformly mixed in solid state
Brass is an alloy in which copper and zinc are distributed uniformly throughout the material while the mixture remains in the solid state. A solid solution therefore has a solid solvent and solute mixed at the particle level without separate visible layers. Water, gas release, and the presence of only zinc do not explain brass’s classification. Hence option A is correct.
