A disproportionation reaction is one in which a species has been both oxidised and reduced (that is, the oxidation state of the related species found in the products has increased in one instance, and decreased in another, in relation to that of the species found in the reactants).
The classic example of disproportionation is the reaction between chlorine gas and dilute sodium hydroxide, although there are many others:
Cl2 + 2NaOH --> H2O + NaCl + NaClO
The oxidation state of chlorine is 0 in the reactants, but has decreased to -1 in NaCl AND has increased to +1 in sodium chlorate, NaClO.

∙ 12y agoIn a disproportionation reaction, the same reactant is both oxidized and reduced. In other words, atoms of a substance lose electrons to a different atom of the same substance. Here's an example:
3 Cl2 + 6 OH− --> 5 Cl− + ClO3− + 3 H2O
As a reactant, chlorine has an oxidation state of 0. After the reaction, some have become Cl- with a -1 oxidation state, while others have become a part of ClO3-, in which Cl has an oxidation state of +5.

∙ 8y agoIn these reaction, an element simultaneously undergoes oxidation as well as reduction. This is possible only when the element exhibits minimum three different oxidation states and on the reactant side, it is present in an intermediate oxidation state while higher and lower oxidation states are exhibited by it in the form of products.

What kind of reaction breaks a substance into simpler substances?
A "decomposition" or "disproportionation" reaction.
What is another name for oxidation-reduction reaction?
another name for an exchange reaction but metathesis reaction. This reaction usually occurs in hydrolysis and is AB+CD=AD+CB
What happens when HNO2 undergoes disproportionation?
Disprotonation? Donates a proton. To give, H(+) and NO2(-)
What is a chemical reaction that breaks down compounds into simpler products?
When chemicals are combined or broken down, they go through reactions. The combination is called a synthesis reaction and breaking down is called a decomposition reaction.
Disproportionation of chromium oxide in acid?
6CrO2 (aq) + 10 H+ (aq) --> Cr O72- (aq) + 4 Cr3+ (aq) + 5H2O (l)
What is a Cannizzaro reaction?
A Cannizzaro reaction is the disproportionation of an aldehyde into an alcohol and carboxylic acid.

What is it called when an element is simultaneously oxidised and reduced in a reaction?
disproportionation
What is the Cannizzaro reaction?
A Cannizzaro reaction is the disproportionation of an aldehyde into an alcohol and carboxylic acid. The Cannizzaro reaction, named after its discoverer Stanislao Cannizzaro, is a chemical reaction that involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to give a primary alcohol and a carboxylic acid. Named after: Stanislao Cannizzaro

Is NH4NO3 N2O H2O a disproportionation reaction?
This is a thermal decomposition reaction.

Disproportionation of chromium oxide in acid?
6CrO2 (aq) + 10 H+ (aq) --> Cr O72- (aq) + 4 Cr3+ (aq) + 5H2O (l)
In the chemical equation H2O2(aq)-H2O(1) plus O2(g)then H2O2 is a?
If you had the equation of H2O2(aq) ==> H2O(l) + O2(g), it wouldn't be balanced, so is incorrect. If it were 2H2O2 ==> 2H2O + O2, then it would be balanced, and H2O2 would be an example of a disproportionation reaction, where H2O2 is both the oxidizing and reducing agent, i.e., the O is both oxidized and reduced to form H2O and O2. Not sure if this is what you are looking for as the question is rather vague.
Does an oxidizing agent become oxidized?
The term oxidation is named after oxygen, which is the most common oxidizing agent. Oxygen has a strong attraction for electrons, and in most chemical reactions it will take two electrons away from another atom (or from two atoms, such as in the case of the famous water molecule which is composed of one oxygen atom and two hydrogen atoms). So when an atom loses one or more electrons, it is oxidized.
What are some science words that start with the letter D?
