What is a chemical property? A property is a quality that comes to light during a chemical reaction. To establish the quality, we have to change the chemical identity of the substance. Here are some common properties of materials and how they are related to each other. Also, we will see the importance of a chemical property to our everyday lives. Read on to discover more! Listed below are a few examples of properties:


Reactivity is a property that describes the ability of a substance to undergo chemical reactions. It can be explained by several theories, such as the valence bond theory or the atomic orbital theory. In simple terms, chemical reactions occur when the products are at a lower free energy than the reactants, resulting in a lower-energy state, known as a stable state. The most comprehensive explanation of chemical reactions is found in quantum chemistry, in which electrons exist in orbitals that are determined by solving the Schrodinger equation.

Reactivity is a general property of substances. It describes the rate and extent to which one chemical substance reacts with another. It can occur in the same molecule, in different atoms, or in a mixture. It is usually followed by a loss of energy. Highly reactive elements undergo rapid and violent reactions that can cause explosions. In addition to the chemical property of substances, reactivity is also measured in terms of atom size. The larger an atom is, the more reactive it will be.


The chemical property of flammability refers to the ability of a substance to burn or ignite. The test determines how easily a chemical can burn and the degree of difficulty required to start combustion. Liquids, solids, and gases are categorized as highly, moderate, or low flammability. This information is usually found in the section 9 of a safety data sheet (SDS). This information is crucial when storing and handling flammable substances, because precautions must be taken to prevent fire and other hazards. The Globally Harmonized System (GHS) outlines detailed classification criteria for flammable gases, liquids, and solids.

The chemical property of flammability can also be defined as a substance’s reactivity, or how easily a substance will react with another substance. For example, when iron reacts with oxygen, it will form rust. The flammability of a substance is important in determining whether it will burn or react with another substance. If it burns, its flammability means that it will burn, so the property of flammability is an important part of determining the safety of a product or substance.


Hardness is a physical property that describes the ability of a material to resist the forces of physical phenomena. This property is a qualitative characteristic of matter, but it can also be a quantitative one. Hardness is measured by measuring how resistant a material is to scratching, cutting, and abrasion. However, the actual value of hardness is often not the same as the amount of material that makes up the sample.

Hardness is measured in units of N/mm2. However, it must not be confused with pressure. Because hardness can be a measurable quantity, different scales are used to measure this property. Other properties of matter are color, mass, length, malleability, melting point, odor, temperature, and toxicity. Hardness is one of the least understood physical properties. However, it is important to note that color has little or no relationship with hardness.

Melting point

The melting point of a solid is dependent on the chemical and physical properties of the substance. All metals possess different melting points, but they all have one common chemical property: the intermolecular force of attraction. When a solid or liquid is melted, it requires energy to melt. The energy required for melting is proportional to the amount of material in the solid or liquid. Hence, the melting point of a solid is lower than that of a liquid.

The melting point of a solid is the temperature at which the substance changes from a solid to a liquid. In addition, it also determines the purity of the substance. This physical property is very important because it is often used to comment on the purity of a substance. This property is an important part of scientific research. However, it does not always reflect the exact nature of a substance. In fact, it can also change its composition.

Catalytic property

Chemical properties can be categorized according to their physical, catalytic and reactivity. For instance, iron combines with oxygen in water to form rust. Chromium does not oxidize, and neon is unreactive. In addition, physical properties can be discerned without drastically altering the substance’s structure. In this way, physical properties help determine which chemical products are most suitable for certain purposes.

Silver and copper are two examples of catalysts, with different applications. In the production of formaldehyde, silver catalysts are used to make a substance called formaldehyde. Formaldehyde is a building block in many solid plastics adhesives and laminating resins. It also helps produce finishes on paper and electronic equipment. It is also used in coatings that resist heat, and in the production of dinnerware, toys, and casings.
