Interpretation Introduction
Interpretation:
Type of solution formed by dissolution of
Concept Introduction:
A homogeneous mixture of more than two substances is known as solution. It can exist in any of phases. It has two components, solute, and solvent. Component that is present in small quantity and that dissolves itself into other component is called solute. Component that exists in larger quantity and that dissolves solute in itself is called solvent.
