SOLUTIONS

 

Ø A homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility.

 

Ø The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible. 

Ø Air, for example, is a solution consisting chiefly of oxygen and nitrogen with trace amounts of several other gases, and brass is a solution composed of copper and zinc.

 

 

Homogeneous mixtures:

Ø homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample.

 

Heterogeneous mixtures:

Ø Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample.
