What is a Chemical Change?

  • A chemical change is a change of materials into another, new materials with different properties and one or more than one new substance are formed.
  • It results when a substance combines with another to form a new substance (synthesis or either decomposes to form more substances) . The oxidation reaction is a chemical change example that causes a chemical reaction.
  • Chemical changes are mostly irreversible except by further chemical reactions. Examples are dye in the colour and creating a chemical change in the hair. There are three types of chemical changes namely organic, inorganic and biochemical change.

Chemical Change Examples

Examples of Chemical Change in Everyday Life

Chemical changes happen around us all the time and not just in a chemistry lab. Some chemical change examples in our everyday life are mentioned below.

  • Burning of paper and log of wood
  • Digestion of food
  • Boiling an egg
  • Chemical battery usage
  • Electroplating a metal
  • Baking a cake
  • Milk going sour
  • Various metabolic reactions that take place in the cells
  • Rotting of fruits
  • Decomposition of waste
  • The explosion of fireworks
  • The reaction between salts and acids.
  • Rusting of iron
  • Lightening a matchstick
  • Combustion of wood
  • The metabolism of food in the body
  • Mixing an acid and a base, such as hydrochloric acid (HCl) and sodium hydroxide (NaOH)
  • Cooking an egg
  • Digesting sugar with the amylase in saliva
  • Mixing baking soda and vinegar to produce carbon dioxide gas
  • Grilling a hamburger

Chemical changes may cause a substance to:

  • Change color
  • Change temperature
  • Produce bubbles
  • Produce Precipitate

Chemical Changes Involving Organic Compounds

Organic Compounds are complex compounds of carbon in which one or more atoms are covalently linked to atoms of other elements. Some of the examples of chemical change involving organic compounds are stated below.

Burning of a Natural Gas

This is a clear example of a combustion reaction. Natural gas comprehends methane gas. When methane reacts with oxygen in the atmosphere it produces water and carbon dioxide. Hence it is an example of chemical change.

Ripening of Fruits

It involves a series of changes. Fruits consist of ethylene. There is an increase in ethylene production when fruit gets damaged or when it is plucked. This results in the production of new enzymes which in turn reacts with the chemical present on the fruit. So, the fruit may witness several changes. Some changes are mentioned below.

  • The fruit becomes juicier and softer.
  • Due to the breakdown of chlorophyll, the outer skin of fruit changes its colour.
  • Tdiffersiffer, i.e.. , it changes from sour to sweet.
  • The aroma is emitted from ripe fruit.
