Question

Water contains hydrogen and oxygen in the ratio of 2:1. prove it by an

activity.​

Answer 1

Answer:

Answer. The perfect example demonstrating this is the electrolysis of water. If we take some water in a beaker and add sulphuric acid to it then it becomes acidulated water and a great conductor of electricity. ... This proves that water has 2 parts of hydrogen and 1 part of oxygen.

Answer 2

hydrogen valency = 1... it contain two hydrogen atoms so valency of h²=2*1=2

Oxygen valency = 1

so 2:1
