EVERYDAY SCIENCE

Detailed explanation-1: -A solution is a mixture that is the same or uniform throughout. Think of the example of salt water. This is also called a “homogenous mixture.” A mixture that is not a solution is not uniform throughout. Think of the example of sand in water. This is also called a “heterogeneous mixture."

Detailed explanation-2: -A heterogeneous mixture is a mixture where throughout the solution the composition is not uniform. By definition, a single-phase consists of a pure substance or a homogeneous mixture. There are two or more phases of a heterogeneous mixture.

Detailed explanation-3: -The substances in a heterogeneous mixture are not evenly mixed. In one part of the mixture, there may be more of one substance than in another part. Often, the different substances in such a mixture can be seen. You can “pick out” the substances in a heterogeneous mixture, even if you have to use a microscope.

Detailed explanation-4: -Scientifically speaking, a homogeneous mixture is one in which different parts (such as salt and water) have been uniformly combined into a new substance (salt water), while a heterogeneous mixture has parts that remain separate.

Detailed explanation-5: -In most technical applications homogeneous means that the properties of a system are the uniform throughout the entire system; heterogeneous (also inhomogeneous) means that the properties change within the system. Any system with two phases like ice and water are said to be heterogeneous.
