SOLUTE

solute: the substance that dissolves in a solvent to produce a homogeneous mixture.

Saturated solution: A solution in which no more solute can be dissolved at a given temperature and pressure.

Unsaturated solution: A solution in which more solute particles can be dissolved at a given temperature and pressure.

Solute: The particles which are dissolved in a solution are called solute particles...

Solvent: The substance in which solutes are dissolved in a solution is called solvent...

Solution: A homogeneous mixture of two or more substances in relative amounts is called solution.
