The answer is solute, solvent 

In a solution, a solute the component which is present in lesser amount while a solvent is present in greater amount.  Since nitrogen is present in a greater amount than oxygen (78% > 21%), then the oxygen must be the solute and the nitrogen must be the solvent in the air.
