Anton Robles · Answer 1

A) solute - NaCl, solvent - water

B) solute - O2 and other gases, solvent - N2

C) solute - ethanol, solvent - water

D) solute - tin, solvent - copper

Explanation:

Solute (s) is/are the minor component (s) in a solution, dissolved in the solvent.

Solvent is the component of a solution that is present in the greatest amount. It is the substance in which the solute is dissolved.

If both solute and solvent exist in equal quantities (such as in a 50% ethanol, 50% water solution), the concepts of "solute" and "solvent" become less relevant, but the substance that is more often used as a solvent is normally designated as the solvent (in this example, water).
