Full Answer
How does hydrogen peroxide react with water?
There are various benefits from using hydrogen peroxide as a disinfectant in water treatment:
- It leaves no trace of chemical residues because the peroxide decomposes fully
- It is biodegradable because it disintegrates into water immediately
- It removes any odours in water caused by hydrogen sulphide gas
- It cleans organic deposits from irrigation systems
- It is environmentally safe, as it does not pollute water or contaminate soils.
What happens when hydrogen reacts with oxygen?
Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. As the products of the reaction are at a lower energy level than the reactants , the result is an explosive release of energy and the production of water.
How do you combine hydrogen and oxygen?
To combine hydrogen and oxygen to make water, you basically have to mix the gases together and light them with a match. Just mixing the gases together isn't enough - you have to do something to get the chemical reaction started. The problem is that this creates a big explosion.
What are the side effects of hydrogen peroxide therapy?
- The tissues inside your mouth are affected and become sensitive as a result of hydrogen peroxide overuse.
- Porous dental work that has been done, such as cementing or dental amalgams, are likely to be damaged with the use of hydrogen peroxide.
- Throat soreness is another common side effect of hydrogen peroxide, if swallowed by mistake while gargling.

Why is hydrogen peroxide a powerful oxidant?
The selective reduction of oxygen to water in such biological systems is crucial, not only in order to maximize the energy produced for cellular metabolism but also because hydrogen peroxide is a powerful oxidant and cytotoxin, which harms living cells.
What happens when hydrogen and oxygen combine?
When molecular hydrogen (H 2) and oxygen (O 2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right. Chemists use redox half-reactions to describe thermodynamic processes like the ones embodied by such equations. For both of the reactions shown, the hydrogen molecules are oxidized and the oxygen atoms are reduced. Accordingly, each of the reactions below is described by a combination of two half-reactions--one corresponding to a chemical oxidation and another corresponding to a reduction.
How many electrons are needed for hydrogen oxidation?
The redox half-reaction for hydrogen oxidation is relatively simple and is shown on the left side of the scheme below. In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons. Writing a half-reaction for oxygen reduction is more complicated, since oxygen can be reduced by either one, two or four electrons, as shown by the square redox scheme to the right, below. In most chemical reactions, molecular oxygen is reduced along the red and blue pathways highlighted in this redox scheme. The complete reduction of O 2 by four electrons (4e - + 4H +, blue horizontal pathway) generates two equivalents of water whereas the corresponding two-electron reduction (2e - + 2H +, red diagonal pathway) yields hydrogen peroxide. Both the two- (¿G¿ = -0.695 V) and four-electron (¿G¿ = -1.229 V) reductions of O 2 are energetically downhill, but more than half a volt of energy is squandered in the former reaction. Accordingly, biological processes coupled to O 2 reduction, such as cellular respiration, are highly selective for the complete 4e - + 4H + pathway in order to maximize the energy available for ATP synthesis. The selective reduction of oxygen to water in such biological systems is crucial, not only in order to maximize the energy produced for cellular metabolism but also because hydrogen peroxide is a powerful oxidant and cytotoxin, which harms living cells.
