Answer:
Let me explain this to you with a simple example:-
Let's take Water and Salt,
When we mix both water and salt we get a solution.
Salt gets dissolved in water. Therefore, the substance which gets dissolved is called the solute. So here, Salt is the solute.
Water is dissolving the salt. Therefore, the substance that is dissolving the solute is called the solvent.
Solute + Solvent = Solution
