10 Examples of Chemical Properties

The reaction of a substance , molecular changes and oxidation , are some examples of chemical properties of matter. Therefore, it is the ability of an element to transform itself in the presence of external or reactive agents.

Likewise, when reacting on another substance, the elements in question change their property directly proportional to the experimental action. 

Examples of chemical properties of matter

1. Reactivity

One of the examples of the chemical properties of matter is reactivity , a process by which one substance actually reacts with another. 

For example, when lithium reacts on hot water , it causes a chain effect that stimulates the release of other simpler components. 

In the same way, it happens with water if it is influenced by external elements, they can trigger a state of rupture in its molecular structure ( hydrolysis ). 

Therefore, reactivity is one of the most applied chemical processes and with this, possible changes of a certain structure are identified. 

2. Oxidation

It is a chemical process where a substance intervenes that eliminates electrons , transforming the chemical structure of a body. 

Therefore, when the substance comes into contact with an oxidizing reagent, a chemical reaction occurs and the properties of the body change dramatically. 

An example of this process is when the decomposition of electrons is carried out in a metal, that is, iron , which is transformed into ferric oxide. 

3. Reduction

The following chemical process transforms a reaction into electron gain on an element in question. 

Consequently, the atom achieves electrons and causes a low interaction with the oxidation process. 

Likewise, the reduction acts on chemical bonds such as those of oxygen and carbon , causing a substantial increase in hydrogen atoms 

4. Hydrolysis

The word ‘ lysis’ is death, destruction or rupture and ‘ hydro’ , means water. Therefore, it is the breakdown of a molecule or ion of the vital liquid. 

Said chemical reaction or interaction occurs as a result of a hydric molecular dissociation, forming union with other elemental bonds. 

In turn, the water molecule breaks or divides into various structures, creating other reactions starting from the fragments of the original configuration. 

5. Combustion

This chemical reaction is due to external elements such as light and heat, causing considerable changes in a body or matter. 

This chemical property is related to the oxidation of the elements, which quickly act as ‘ fuels’ 

An example of combustion is the complete oxidation of the elements creating other compounds such as carbon dioxide or water. 

On the other hand, carbon monoxide and hydrogen particles are elements resulting from incomplete combustion. 

6. Flammability

This process occurs with the external conditions of pressure temperature and the emission of gases where a body or combustible material is involved. 

Therefore, combustion and flammability are chemical processes derived from oxidation. 

To cite an example, since fire exists as a combustible substance , liquid gas is added , the flammability process is directly proportional to the temperature. 

Starting from the previous idea, the chemical property of a flammable object will depend on the extreme temperature or heat of a physical agent. 

7. Alkalinity

Another example of chemical properties of matter is alkalinity, an action that allows the acid components of a substance to be neutral. 

One of the examples of this chemical reaction is water, which must be neutralized to be drinkable and then suitable for human consumption. 

On the other hand, the alkalinity of water is based on the presence of weak acids that react to any natural or chemical stimulus. 

8. Ionization 

This chemical process owes its name to the production of positive ions as opposed to neutral elements or to their deficit. 

For this, there must be an imbalance in the presence of neutrons , passing this procedure, the ions can be anion or cation 

In the case of the anion, it consists of the presence of a negative electric charge, which allows the entry of electrons previously obtained. 

For its part, the cation is an ion with a positive electric charge and that constitutes the deficit of electrons through a previous chemical reaction. 

9. pH measurement

The pH is the interpretation of a substance using a scale that goes from 0 to 14 and that will consider if it is alkaline (basic), neutral or acidic .

If the substance is less than 7 it is considered an acid, which dictates the concentration of hydrogen in a liquid. 

On the other hand, if it exceeds 7, we are in the presence of an alkaline aqueous substance. 

Meanwhile, the neutral pH considers the balance existing in the alkaline and acid reactions of a chemical component.

10. Esterification 

The formation of esters is called ‘ esterification’ , where essential components such as fatty acids and alcohol are involved 

The carboxylic acids bind with alcohol and in turn, generates a reaction equivalent to the formation of esters 

Some examples of this chemical process are vinyl acetate, methyl salicylate or glyceryl trinitrate and acetylsalicylic acid or aspirin very useful in medicine.
