What statement best describes miscible substances?

• A. They dissolve in each other.
• B. They do not mix.
• C. They react to form a new compound.
• D. They change color when mixed.

Answer: (A)

Miscibility describes how liquids mix together. If two liquids are miscible, they dissolve in each other in all proportions to form a single, uniform phase. Water and ethanol are a classic example: any amount of ethanol can be mixed with water and a homogeneous solution results, with no separate layers. In contrast, immiscible liquids like oil and water separate into distinct layers. The statement that best describes miscible substances is that they dissolve in each other. The other ideas describe immiscibility (they do not mix), a chemical reaction (they form a new compound), or a color change upon mixing (not a defining feature of miscibility).
