What is the Difference Between H2O and H2O2?
🆚 Go to Comparative Table 🆚The main difference between water (H2O) and hydrogen peroxide (H2O2) lies in their chemical composition and properties. Here are the key differences:
- Composition: Water is composed of 2 hydrogen atoms and 1 oxygen atom, while hydrogen peroxide has 2 hydrogen atoms and 2 oxygen atoms.
- Oxidation State: In water, the oxygen atom has a -2 oxidation state, whereas in hydrogen peroxide, each oxygen atom has a -1 oxidation state.
- Boiling Point: Hydrogen peroxide has a higher boiling point than water.
- Chemical Properties: Hydrogen peroxide is a strong oxidizing and reducing agent, while water is a good solvent. Hydrogen peroxide can cause fizzing reactions with certain substances, such as bacteria, while water does not.
- Acidity: H2O2 gives off 2 hydrogen ions in an aqueous solution, while water gives off only 1 hydrogen ion.
In summary, water and hydrogen peroxide are made of the same elements, hydrogen and oxygen, but they have different compositions and properties. Water is a fundamental molecule for life, while hydrogen peroxide is known for its strong oxidizing and reducing properties.
Comparative Table: H2O vs H2O2
Here is a table comparing the differences between water (H2O) and hydrogen peroxide (H2O2):
Property | Water (H2O) | Hydrogen Peroxide (H2O2) |
---|---|---|
Chemical Formula | H2O | H2O2 |
Elements | 2 Hydrogens and 1 Oxygen (H2O) | 2 Hydrogens and 2 Oxygens (H2O2) |
Physical State | Liquid | Liquid |
Color | Clear | Clear |
Odor | Odorless | Slightly sharp or pungent |
Water (H2O) and hydrogen peroxide (H2O2) are both clear liquids made of hydrogen and oxygen atoms. The main difference between them is the number of oxygen atoms in their molecules: water has one oxygen atom, while hydrogen peroxide has two oxygen atoms. This difference in the number of oxygen atoms results in hydrogen peroxide having a slightly sharp or pungent odor, unlike the odorless water.
