Solutes and Solvents

Q.

What are aqueous solutions?

Q. What is solvent and solute?

Q. What is a solute?

Q.

We know, in a solution the substance present in the smaller quantity is called the solute and the substance present in larger amount is called solvent. But what if both the constituents of the solution are in equal amount ? Suppose we have a liquid in liquid solution in which both the constituents are in equal amount then which one would be solute and which one would be the solvent in that particular solution?
