Water is a compound because if we pass electricity through it then at two different electrodes, we get two different gases i.e., oxygen and hydrogen during electrolysis of water. The ratio of oxygen:
hydrogen is 1 : 2 by number of molecules.
- The properties of oxygen and hydrogen gases sire entirely different from that of liquid water.
- The ratio of oxygen: hydrogen combination is always constant i.e., 1: 2 by volume.
- To separate the components of water, we need electrolytic cell, and it is not a simple process.
