Question

an air which one is solute and which one is solvent? why?​

Answer 1

Answer:

Air is a mixture of nitrogen, oxygen, argon and other gases. If one simplifies its composition, it is a mixture of nitrogen and oxygen. In a mixture, the majority component is the solvent and the minority component(s) is the solute. Nitrogen is the solvent and oxygen (and all the other minor components) is the solute.
