Examples for Chemical Reaction in Everyday Life

Chemical reactions can happen anywhere around us, not just in the laboratory. Matter interacts to form new products through a process called chemical reactions or chemical changes. Every time we cook or are cleaning, it is also a chemical in action. Our bodies live and grow thanks to chemical reactions. There are reactions when we take drugs, light a match, and take a breath. Here are 10 examples of chemical reactions in everyday life. This is just a small example, because we see and experience hundreds of thousands or even more chemical reactions every day.

1.   Burning

Every time we light a match, burn a candle, make a fire, or light a grill, we will see a burning reaction. Combustion combines energetic molecules with oxygen to produce carbon dioxide and water.

For example, propane combustion reactions, found in gas grills and some fireplaces, are:

C₃H₈ + 5O₂ → 4H₂O + 3CO₂ + Energy

2.   Corrotion

Rust is iron oxide, usually a red oxide formed by redox reactions of iron and oxygen in the presence of water or air humidity. Some forms of rust are distinguished both visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron (III) oxide Fe₂O₃ · nH₂O and iron (III) oxides-hydroxides (FeO (OH), Fe (OH)₃).

In sufficient time, oxygen, and water, every iron mass will eventually convert entirely of rust and crumbling. The rust surface is flaked and brittle, and does not provide protection to the base iron, such as the formation of patina on the surface of the copper. Rust is a general term for corrosion of iron and its alloys, such as steel. Many other metals have equal corrosion, but the resulting oxide is not commonly called rust.

Here is the chemical equation for iron rust:

Fe + O₂ + H₂O → Fe₂O₃. XH₂O

3.   Mixing of Chemicals

If we just combine vinegar and baking soda to make chemical volcanoes or milk with baking powder in a recipe, we experience the displacement or double reaction metathesis (plus some other things). The material recombines to produce carbon dioxide and water gases. The form of carbon dioxide bubbles in the volcano and can help increase roasting.

These reactions seem simple in practice, but often consist of several steps. Here is the overall chemical equation for the reaction between baking soda and vinegar:

HC₂H₃O₂ (aq) + NaHCO₃ (aq) → NaC₂H₃O₂ (aq) + H₂O (l) + CO₂ (g)

4.   Batteries

Batteries are electrical-chemical devices that store energy and emit energy in the form of electricity. A battery usually consists of three important components, namely:

Ø  The carbon rod as anode (the positive pole of the battery)

Ø  Zinc (Zn) as cathode (negative pole of battery)

Ø  Pasta as electrolyte (conductor)

Batteries use electrochemical or redox reactions to convert chemical energy into electrical energy. Spontaneous redox reactions occur in galvanic cells, while chemical reactions do not occur spontaneously in electrolytic cells.

5.   Acid and Bases Reaction

Whenever we mix acid (eg, vinegar, lemon juice, sulfuric acid) with a base (eg, baking soda, soap, ammonia, acetone), we do acid-base reactions. This reaction neutralizes acids and bases to produce salt and water.

Sodium chloride is not the only salt that can be formed. For example, here is the chemical equation for an acid-base reaction that produces potassium chloride, a substitute for common table salt:

HCl + KOH → KCl + H₂O

6.   Soaps and Detergens

Soaps and detergents can be cleaned by using chemical reactions. Soap emulsifies dirt, which means soap binds stain oil stains so they can be cleaned with water. The detergent acts as a surfactant, lowering the surface tension of the water so it can interact with oil, isolate them, and and clean it.
