Why is pure water not a mixture?
A mixture is when two or more substances combine physically together.
However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.
Therefore, water is not a mixture; it is a compound and it is pure..
Is tea a mixture?
A Tea is a solution of compounds in water, so it is not chemically pure. It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture. A Orange juice contains particles of solid (pulp) as well as liquid; it is not chemically pure.
Is salt water a pure substance?
Ordinary table salt is called sodium chloride. It is considered a substance because it has a uniform and definite composition. … Water is also a pure substance. Salt easily dissolves in water, but salt water cannot be classified as a substance because its composition can vary.
Is pure water solution?
Yes, pure water is a solution. …
Is pure air a mixture?
Pure air – Solution – uniform physical combination of gases such as nitrogen, oxygen, carbon dioxide, and argon. Oxygen – Element – found on the periodic table being composed of one type of atom. Salad dressing – Heterogeneous mixture – visibly differing parts as the oils, waters, etc.
Is Vinegar a mixture?
Vinegar is an example of a homogeneous mixture, and not a pure substance since water, its solute, is dissolved in the solvent, being acetic acid. Homogeneous mixtures are also known as solutions, which are mostly composed of liquids (including vinegar), but can include gases.
Why is oxygen not a mixture?
Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element – oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.
What is chemically pure water?
In the United States, the EPA defines “pure” water as water free from all types of bacteria and viruses. … Water is a compound made up of hydrogen and oxygen, so pure water would be water that contains nothing but hydrogen and oxygen.
What mixture is pure water?
Water, H2O, is a pure substance, a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.
Is sugar and pure water a mixture?

Is Salt NaCl a mixture?
A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements. When salt is added to water to make saltwater, it becomes a mixture.
Is iced tea a mixture?
A heterogeneous mixture is made of different substances that remain physically separate. … A glass of iced tea is a heterogeneous mixture. The ice cubes have different composition and properties than the tea. You can say that the ice cubes are a solid phase, and the tea is a liquid phase.
Is sugar and tea a mixture?
