Mixture
In chemistry a pure substance consists only of one element or one compound, but a mixture
consists of two or more different substances and not chemically joined together. Or it also can
be defined as combination of two or more constituents which joined without chemical
reaction. The components of a mixture can be separated without chemical reactions. For
example, shows in figure 2.7, there are many balloons of different colors tied together. The
balloons are then separated according to their color. Now several groups of balloons can be
seen with different colors.
Figure 2.6: Balloons separated according to different color
Hydrogen, H and Oxygen, O are both gases. Together, as a mixture, hydrogen and oxygen
can react and form water, H2O. Water is a compound of hydrogen and oxygen. There are
important differences between the properties of a mixture and a compound.
In Table 2.6, the column 'Mixture' refers to the gas hydrogen and oxygen, and the column
named 'Compound' refers to water.
