A mixture is a combination of two or more substances that retain their own identity.

The term homogeneous means that the substances in the mixture are uniformly distributed. (For example, when you are baking a cake, you mix flour, sugar, baking soda, etc., and you put them in a bowl, forming a mixture. Until you stir it up, however, it will not be homogeneous, because the ingredients are not distributed evenly. After you mix it up, it will be a homogeneous mixture with uniform characteristics (cake batter). But at the microscopic level, there are still individual particles of flour, sugar, baking soda, etc.

A chemical example of a homogeneous mixture would be a substance that is dissolved in water and uniformly mixed. For example, when you dissolve NaCl (sodium chloride--table salt) in water, it dissolves and (eventually) distributes itself evenly throughout the container. The mixture will contain water molecules, sodium ions (Na+) and chloride ions (Cl-), so it will be a mixture of different substances. But they will be uniformly distributed, so it will be homogeneous.

Is methanol a heterogeneous or homogeneous mixture?

A heterogeneous mixture is a sum of pure substances which are not soluble in each other while a homogeneous mixture is a mixture wherein its constituents do not appear separately. Methanol is an example of a homogeneous mixture.


Is air a homogeneous mixture?

Yes, air is considered a homogeneous mixture because it is made up of a combination of gases, such as nitrogen, oxygen, carbon dioxide, and others, that are uniformly distributed throughout. This means that the composition of air is consistent throughout its volume.


Is mouthwash a compound element homogeneous mixture or heterogeneous mixture?

Mouthwash is typically a homogeneous mixture. This means that the components are evenly distributed throughout the solution and the mixture has a uniform composition.


Is lemonade an element a compound a homogeneous mixture or a heterogeneous mixture?

Is gasoline a homogeneous compound or a mixture?

It is a homogenous mixture, because it is a mixture of a few different hydrocarbons.Gasoline is a homogeneous mixture.A heterogeneous mixture is one that consists of two or more substances; it is non-uniform and the components of the mixture can be seen. Vegetable soup is an example of this type of mixture.A homogeneous mixture has uniform composition and properties throughout. Salt added to water and stirred until it dissolves is a heterogenous mixture. Air is a homogeneous mixture of gases.Gasoline like most clear liquids is homogenous (of one nature or of a uniform nature). Windex, blood and milk are other examples of homogenous mixtures.Heterogenous mixtures are anything that is not uniform in its composition, some everyday examples are: sand in water, vinegar and oil, and a bowl of oatmeal.
