Water is known as universal solvent essential for all organisms to survive. It keeps the living organism hydrated. Water is colorless, odorless, transparent, tasteless exist gaseous, liquid, and solid states. People are confused about the water either it is mixture or compound. Water is made of two hydrogen atoms and one oxygen atom linked by covalent bonding. It is formed by reaction of hydrogen atom and oxygen atom.
2H + O → H2O
Compounds are substances that are atoms and different elements united together by the chemical bond. The chemical bond in compounds can be covalent or ionic or metallic. As we know that water is made of chemical bonding between hydrogen and oxygen elements that why it is a compound not a mixture.
Water is also known as a molecule because a molecule is a group of atoms bonded together by a chemical bond. Normally hydrogen and oxygen are elements but they also exit as molecule H2 and O2 and in water formation, they form bonds with each other, water is a molecule.
Why Water is a Compound
There are following properties that explain why water is a compound
- Water contains atoms of different elements which can be formed by chemically combining two or more elements.
- Water can be separated into simpler substances (components) by chemical reactions.
- The properties of water are unique to themselves and different from the properties of their components as the elements in the water are in fixed
- Water have specific mass ratios with defined manner
Why water is not Mixture
There are following properties that explain why water is not a mixture.
- A mixture is a combination of two or more substances that are formed by physically mixing two or more substances.
- The components in mixtures are different elements so the ratio is not fixed.
- The constituents of a mixture do not lose their properties and so, the properties of a mixture depending on the type of substance and quantity of substance
- A mixture can be separated into simpler substances by physical or mechanical methods more easily than compound
