A heterogeneous mixture

In this blog we are going to learn about a heterogeneous mixture .To know more about this concept go for online free chemistry help.

what a 'mixture' is. Very simply a mixture is a combination of two or more elements in no particular ratio. For example Air is a mixture of many gases like carbon dioxide, oxygen, nitrogen, etc. Another examples of mixture ,a solution of salt in water, a mixture of sand and salt etc.

The components of the mixture exhibit their own chemical properties in the mixture. Like say in a mixture of salt and sand, graininess of sand and the crystalline nature of salt are retained.

Components of a mixture, easily separated using physical means like filtration.

There is no evolution of energy during the formation of a mixture.

A heterogeneous  is a mixture where each component exhibits of its physical and chemical properties in the mixture. Take a mixture of sulphur powder and dust of iron. We clearly able to see yellow particles of sulphur powder and reddish brown particles of iron dust. Now bringing a magnet near to that mixture , iron dust will attracted to it and sulphur powder will stay there only. Other examples of heterogeneous mixtures is  sand and sugar.
