Hi! Thanks for your question. But as you have posted multiple questions, I am answering only the first one for you. If you need help with the other questions too, please repost them separately.
A liquid that dissolves a solid, liquid or gaseous solute is referred to as a solvent. A substance that is dissolved in another substance is known as a solute. A solute and a solvent together make up a solution.
In a solution, both the solvent and the solute are in the liquid phase, the solvent is the one which is present in greater amount than the solute.
