What properties can be used to identify substance and why?

Characteristics such as melting point, boiling point, density, solubility, color, odor, etc.

These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness. Chemical properties tell us how the substance interacts with other substances and may include reaction with oxygen (oxidation), chlorine, metals, etc..

All substances can be characterized by their unique sets of physical and chemical properties. Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc.
