1. most fruit juices are a solution of water, sugar, and fruit-specific chemicals. in this solution, identify the solvent and solutes.

In this case, we can say that water is the solvent. Solvent by definition are the part of the solution that is present in the largest amount. The fruit juice are all dilute by the water. Everything else in the fruit juice can be called the solute, they are what is "dissolved" in the solvent (sugar, fruit juice, etc.).
