Question

In the electrolysis of water : i) Name the gas collected at the cathode and anode respectively. ii) Why is the volume of gas collected over one electrode double that of gas collected over the other electrode. iii) define the type of reaction involved. plss anyone ans fast

Answer 1

Answer:

your ans dude....

Explanation:

1. During the electrolysis of water:

Gas collected at cathode is → Hydrogen

Gas collected at anode is → Oxygen

2. Hydrogen is collected in the double amount during the electrolysis of water. This is because H2O contains two parts of hydrogen as compared to one part of oxygen by volume.

3. Pure water is a bad conductor of electricity, therefore, by adding drops of sulphuric acid (H2SO4 (dil.)), we make it a good conductor of electricity. So if dil.H2SO4 is not added to water, it would not conduct electricity.
