Multiple Choice
In general chemistry, is lemonade best classified as a solution?
A
No, because it is always a heterogeneous mixture (a suspension) and cannot be homogeneous.
B
No, because it is a pure substance with a fixed composition.
C
Yes, because it is typically a homogeneous mixture of solutes (sugar and acids) dissolved in water.
D
Yes, because it is a colloid with particles large enough to scatter light strongly.
Verified step by step guidance1
Understand the definition of a solution: a homogeneous mixture where the solute particles are uniformly distributed within the solvent at the molecular or ionic level.
Consider the composition of lemonade: it typically contains water (solvent), sugar, acids, and flavor compounds (solutes) dissolved uniformly.
Evaluate whether lemonade is homogeneous or heterogeneous: since the solutes dissolve completely and the mixture appears uniform throughout, it is homogeneous.
Distinguish between solutions, suspensions, and colloids: suspensions have large particles that settle out, colloids have intermediate-sized particles that scatter light, and solutions have particles at the molecular or ionic scale that do not scatter light visibly.
Conclude that lemonade fits the criteria of a solution because it is a homogeneous mixture with solutes dissolved in water, not a suspension or colloid.
