What is a Homeogeneous Mixture?
A homogeneous mixture is a substance composed of two or more different substances that are uniformly distributed at the molecular level. This means that the composition and properties are the same throughout the mixture, and it is often difficult to distinguish the different components by sight. Examples include saltwater and air.
How is a compound similar to a homeogeneous mixture?
In the strictest chemical sense a compound is the term for a molecule, a compound of elements. Sugar, salt and water are examples of compounds. As such compounds have the qualities of consistent color, well defined physical properties (such as melting or boiling point). Compounds cannot be separated because they are of a uniform structure. Homogeneous mixtures are similar to compounds only in appearance. Thus a mixture of sugar and salt may not be discernible from samples of either simply by sight. A better example would be to consider a solution of salt and water. Solutions are also homogeneous mixtures. A saline solution is visually indiscernible from water. In a broader definition, any mixture can be referred to as a compound- if the mixture has a consistent appearance, the two are the same.
Is h2o a heterogeneous mixture?
Water is homogeneous. ------------------------------------------------- Actually natural water is heterogeneous as it is a mixture of H2O and a very tiny amount of D2O. The D2O (i.e. heavy water) has higher mass than H2O and slightly different chemical properties. However for ordinary practical purposes the presence of this D2O can usually be ignored.
