If the solvent is solid and the solute is also solid, what can be a common example?
Answer and explanation
Correct answer: Brass
Brass is a homogeneous alloy formed mainly from the solid metals copper and zinc. In this example, the major solid metal acts as the solvent and the other solid component acts as the solute, so brass is treated as a solid solution. Soda water, salt water, and oxygen in water all contain liquid water as the solvent; consequently, they are not solid-in-solid solutions. Therefore option A is correct.
