Question

What are the characteristics of a mixture?

Accepted Answer

Characteristics of a mixture are as follows:

(i) It consists of two or more substances (elements or compounds or both) mixed together physically.

(ii) It does not have any fixed composition. The components of a mixture are present in different proportions.

(iii) The components of a mixture retain their properties. Thus, it shows the properties of its components. For example, all the components (gases) of air retain their properties. Oxygen supports burning, whereas carbon dioxide is used for extinguishing the fire.

(iv) It does not have any definite property. For example, a mixture of sugar and water does not have fixed properties. The properties can be changed by changing the quantity of sugar or water. (It is important to note that this does not change their individual properties.)

(v) It does not have fixed melting and boiling points. Melting and boiling points depend on the proportions of components of the mixture.

(vi) The components of a mixture can be separated by simple physical methods. It is because they do not combine chemically.

(vii) Generally, energy is neither released nor absorbed during the formation of a mixture.
