Is water a mixture? To answer this understand, we need to understand what a mixture really is. A mixture is any combination of two or more substances that do not cause a chemical reaction. The two types of mixtures are homogeneous and heterogeneous. Some substances such as oil and water are considered immiscible (cannot be mixed together) but they can be forced into an emulsion by the addition of several different chemicals. Is water a mixture? We will answer that later in this article.
What Is a Mixture?
When two or more substances are combined and no chemical reaction occurs, the result is regarded as a mixture. This brings up the question about water. Is water a mixture?
Is Water a Mixture?
Water is not a mixture because the hydrogen and oxygen atoms do combine with each other on the molecular level. Although the atoms can be separated from each other by electrolysis, they were at one time combined by a chemical bond. Therefore water is considered a compound, a molecule made up of two or more elements.
What Types of Mixtures Are There?
Is water a mixture when it is combined with salt? No, but it is one part of the mixture. By most chemical definitions there are only two types of mixtures, homogeneous and heterogeneous. A mixture is regarded as homogeneous when the different types of molecules are evenly distributed throughout, such as salt water. It is heterogeneous when the different substances are not evenly distributed.
Can Oil and Water Ever Combine?
Is water a mixture when it is combined with oil? Oil and water are usually immiscible; they do not mix. When a jar of oil and water is shaken, the two substances will intermingle for a short time until the droplets of oil re-blend into larger globules and finally remove themselves into a separate layer. Many chemical substances are available that can be introduced into the water to prevent the oil droplets from recombining. When the oil droplets remain suspended in water, they form an emulsion.
