Which example is a binary solution based on number of components?
Answer and explanation
Correct answer: Sugar and water
Sugar and water contain exactly two components, and if the sugar dissolves uniformly, they form a binary solution; therefore option A is correct. Salt, sugar and water contain three components and would be ternary if homogeneous. Air contains several gases, while an alloy of three metals has three metallic components, so neither is binary.
