There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. In a homogenous mixture all the substances are evenly distributed throughout the mixture (salt water, air, blood).

In a mixture, all the different parts retain their original properties. A solution is a special type of mixture that is homogeneous, where you cannot tell the difference between the components. A solution is also a special type of mixture that cannot be separated via mechanical means – filtering, screening, etc.

There are three general properties of mixtures. First, components of a mixture can be separated from each other. This makes a mixture different from a compound, in that compounds are chemically combined while mixtures are not.

A compound contains atoms of different elements chemically combined together in a fixed ratio. A mixture is a combination of two or more substances where there is no chemical combination or reaction. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.

Four to be specific, called SOLUTIONS, SUSPENSIONS, COLLOIDS and EMULSIONS.

Mixtures are the substances composed of two or more forms of matter. You can separate them by physical methods. Such examples include a mixture of salt and water, a mixture of sugar and water, different gases, air, etc. In any mixture, the various components do not form through any kind of chemical changes.

Physical properties such as size, shape, color, density, magnetism or the ability to sink or float can be used to separate the substances in a mixture.. Filtration is when matter is passed through a filter and the larger particles are separated out.

A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.

• Mixtures are made up of two or more substances that are not chemically combined with each other . The properties of mixtures are listed below. The components of a mixture each keep their original properties. The separation of components can be easily done.
