A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB → A + B AB → A + B. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.
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.

A decomposition reaction is a type of chemical reaction in which a compound breaks down into two or more substances. It is the opposite of a combination reaction. Sometimes, a complex chemical species breaks down into simple parts. The starting substance is called the reactant, and the resulting substances are called products . General Equation The...
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.
One single reactant and two or more productsRequires energyAn example of a decomposition reaction is the breakdown of carbonic acid (H2CO3) to carbon dioxide (CO2) and water (H2O) . H2CO3 (aq.) → CO2 (g) + H2O (l) This reaction is significant and is responsible for the fizz in soda. Below are some more examples:
Let us take the example of the breakdown of potassium chlorate (KClO3) into potassium chloride (KCl) and oxygen (O2). KClO3 (s) → KCl (s) + O2(g) This equation is unbalanced. In order to balance the equation, we inspect the number of oxygen (O) atoms on the right-hand side of the equation and compare it to the left. We notice that there are two oxy...
The decomposition reaction has a few applications in the industry and daily life. Industry 1. Production of calcium oxide or quicklime 2. Production of lithium oxide 3. Preparation of oxygen and carbon dioxide 4. In metallurgy, for the extraction of metals from their oxides and chlorides through electrolytic decomposition Daily life 1. When a soda ...
Example #1. How to figure out the right (or product side): (1) Identify the type of compound decomposing: NaClO 3 is a chlorate. Notice that you have to be able to "read" a formula and identifiy the parts (cation and anion) that make it up. (2) Apply the rule for that type: chlorates decompose to the binary salt and oxygen gas.
Feb 8, 2021 · Decomposition Reaction Examples. Decomposition reactions are common in daily life. One example is the electrolysis of water to form oxygen gas and hydrogen gas: 2 H 2 O → 2 H 2 + O 2. Another example is the decomposition of hydrogen peroxide to form water and oxygen: 2 H 2 O 2 → 2 H 2 O + O 2. Soft drinks get their carbonation from a decomposition.
Let’s take a look at an example: the electrolysis of sodium chloride (NaCl). 2 NaCl (l) → 2 Na (l) + Cl2 (g) In this reaction, NaCl decomposes into liquid sodium metal and chlorine gas. The 2 half-reactions involved are the reduction of Na + ions and the oxidation of Cl – ions. The setup for the electrolysis of NaCl.
