Question

What are the main characteristics of the heterogeneous mixture?

Answer 1

Hint: It is formed by mixing impure substances. It is a category of matter which reflects the substance type. With reference to equilibrium, it is opposite of the state of reactant and products phase existence. The number of moles are not balanced in reactant and product.

Complete answer:
To find the characteristics of a heterogeneous mixture, we will first classify the matter. Matter is composed of two parts that are pure and impure substances respectively. Impure substances are composed of mixtures. Most of the substances in our surroundings are not in their pure forms and are called mixtures. Mixtures are further divided into homogeneous and heterogeneous. These heterogeneous mixtures are composed of suspension and colloids. These do not have uniform composition throughout. The examples are mixture of soil and stand, mixture of oil and water etc. they can easily be identified because of their visible separated borders. In heterogeneous mixture the characteristics are:
-Most of the mixture are heterogeneous except solutions and alloys.
-The constituent particles are present uniformly in a heterogeneous mixture.
-The component of a heterogeneous mixture can be identified easily.
-generally, two or more phases are present in a heterogeneous mixture.
-particles are sized between one nanometer and one micrometer or more.
 mole = $\dfrac{{volume}}{{22.4L}} $
-they often show a tyndall effect.

Note:
Colloids are heterogeneous but in appearance they seem to be homogenous because the constituent particles in the mixture are very small. The solute particles settle on the bottom of the solvent. In a homogeneous mixture the particles of solute are completely mixed in the layer of the solvent.
