A mixture has uniformly mixed components, but it is not liquid. Which example best supports this statement?
Answer and explanation
Correct answer: Brass
The governing concept is homogeneity: a solution has a uniform composition throughout, but it need not be liquid. Brass is a solid alloy in which copper and zinc are uniformly distributed, so it is a solid solution. Salt water, vinegar, and sugar water also have uniform composition, but they are liquid examples. Brass therefore best proves that a homogeneous solution can be solid.
