A science student prepares a glass of orange juice. The student claims that the juice is a heterogeneous mixture. Which observation best supports this claim?

Question

-All regions of the juice appear identical
-The juice can be separated into water and other substances
-Most of the juice is water
-The last sip of the juice tastes stronger than the first sips

Answer 1

The observation that best supports the claim that the orange juice is a heterogeneous mixture is:

• The last sip of the juice tastes stronger than the first sips.

This observation suggests that the components in the juice are not evenly distributed throughout, indicating that different regions may have varying concentrations of flavors or solutes, which is characteristic of a heterogeneous mixture. In a homogeneous mixture, such as thoroughly mixed solutions, the taste would remain consistent across all sips.
