Differentiate between compound and mixture?
Difficulty: Easy

Distinction between compound and mixture:

Following are the points of difference in a compound and a mixture





 A compound consists of two an impure substance that contains or more elements held together in two or more pure substances that fixed proportions by chemical retain their individual chemical bonds

An impure substance that contains two or more pure substances that retain their individual chemical characteristics is called mixture. A mixture can be converted into two or more pure substances why physical method.


All compounds have fixed melting and boiling points of any and boiling points

Melting and boiling points of any element or compound present in the mixture are quite different to the real ones.


The elements forming the compounds cannot be separated by either physical or mechanical means but with chemical means only

The elements or compounds making the mixture can be easily separated by physical and mechanical means.


When gases react together at constant temperature and pressure to form a compound, change in the volume usually takes place.

When gases are mixed together at a constant temperature and pressure to form a gaseous mixture, no change in the volume takes place.  


The properties of elements making the compound are quite different to those of the compound.

The properties of the mixture are in between the properties of the constituents forming the mixture.


Hydrogen chloride (HCl), glucose (C₆H₁₂O6), carbon dioxide (CO2), etc are compounds.

      i.         Air is the mixture of nitrogen (N2), oxygen (O2), carbon dioxide (CO2) etc.

     ii.         Gun is the mixture of nitre, Sulphur (S) and charcoal.

    iii.         Brass is an alloy and is the mixture of zinc (Zn) and copper (Cu)
