Question

where do you find free electrons in electrolysis of water and why?​

Answer 1

Answer:

Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current.

This technique can be used to make hydrogen gas, a main component of hydrogen fuel, and breathable oxygen gas, or can mix the two into oxyhydrogen, which is also usable as fuel, though more volatile and dangerous.

It is also called water splitting. It requires a minimum potential difference of 1.23 volts to split water.

Answer 2

Explanation:

The electrolysis of water is mainly carried out to yield pure hydrogen and oxygen gases. It involves passing an electric current through the water which results in the decomposition of water into hydrogen and oxygen. ... Water is very weakly dissociated into hydrogen and hydroxide ions.

After electrolysis of water, hydrogen is collected at negative chose and oxygen is collected at positive anode. Hydrogen is double in volume than oxyge
