In general-chemistry terms, is apple juice best classified as a solution?
A
Yes; apple juice is a colloid because it consists of large particles that never dissolve.
B
Yes; filtered apple juice is a homogeneous mixture of substances dissolved in water, so it is a solution.
C
No; apple juice is a pure substance because it contains only one compound.
D
No; apple juice is a heterogeneous mixture because its composition is always visibly nonuniform.
Verified step by step guidance1
Recall the definition of a solution in general chemistry: a solution is a homogeneous mixture where one or more substances (solutes) are uniformly dissolved in another substance (solvent).
Consider the nature of apple juice: it contains various dissolved substances such as sugars, acids, and flavor compounds uniformly distributed in water, making it appear uniform throughout.
Understand that a colloid contains larger particles that do not fully dissolve and can scatter light, often appearing cloudy or heterogeneous, which is different from filtered apple juice.
Recognize that a pure substance consists of only one type of molecule or element, which is not the case for apple juice since it contains multiple dissolved compounds.
Conclude that filtered apple juice fits the criteria of a solution because it is a homogeneous mixture with dissolved substances uniformly distributed in water.
