Some common examples of decomposition reactions are provided below. The decomposition of carbonic acid in soft drinks, which can be represented by the chemical equation H 2 CO 3 → H 2 O + CO 2; The electrolysis of water to yield hydrogen and oxygen. What is the Opposite of ‘Decomposition Reaction’? The opposite of a decomposition reaction ...
Feb 8, 2021 · Decomposition Reaction Definition. A decomposition reaction is a chemical reaction with a single reactant that forms two or more products. The general form of a decomposition reaction is: AB → A + B. A decomposition reaction forms smaller molecules, often including pure elements.
An example of a decomposition reaction is the breakdown of carbonic acid (H 2 CO 3) to carbon dioxide (CO 2) and water (H 2 O) [2]. H 2 CO 3 (aq.) → CO 2 (g) + H 2 O (l) This reaction is significant and is responsible for the fizz in soda. Below are some more examples:
Example \(\PageIndex{1}\): Decomposition Reactions. When an electric current is passed through pure water, it decomposes into its elements. Write a balanced equation for the decomposition of water.

Jan 22, 2014 · A decomposition reaction is complete when the mass of the container and its contents no longer changes on heating. For example, you may wish to determine the mass percent of CO₂ in CaCO₃. You heat the CaCO₃ to decompose it into CaO and CO₂ according to the equation: CaCO₃ → CaO + CO₂.
Jan 12, 2019 · Decomposition Reaction Examples. Water can be separated by electrolysis into hydrogen gas and oxygen gas through a decomposition reaction : 2 HAnother example of this type of reaction is the spontaneous decomposition of hydrogen peroxide into water and oxygen:
Feb 8, 2020 · A decomposition is the opposite or reverse process of a synthesis reaction. Decomposition Reaction Examples. The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction: 2 H 2 O → 2 H 2 + O 2. Another example is the decomposition of potassium chloride into potassium and chlorine gas .
Jun 13, 2023 · The decomposition reactions in intro chemistry classes often result from heating a substance. For instance, when heated or struck, a salt of a complex anion (chlorate, carbonate, azide) may lose a gas (oxygen, carbon dioxide or nitrogen) leaving behind a simpler salt or metal.
