Homogeneous and Heterogeneous Systems
We are about to discuss homogeneous and heterogeneous systems, but first, what is a system? In chemistry, a system is any group of atoms, molecules, ions, & substances. A system can either be homogeneous or heterogeneous. In a homogeneous system, substances are combined such that the components are not easily distinguished by the naked eye. Alcohol solution and sea water are examples of this type of system. To us, sea water is nothing but water. However, it is composed of many minerals, which we cannot see.

In a heterogeneous system, substances are combined such that their components are easily distinguished and their distribution is not constant. An example is a mixture of marbles and beads. In the mixture, you can easily tell apart the marbles from the beads. A terrarium is also a heterogeneous system.
Can you think of other examples of a homogeneous and heterogeneous system?
