Question

During the process of electrolysis of water, the anode is made up of

Answer 1

$\huge\mathscr{\underline{\underline{Answer:-}}}$

Anode is made up of positive charges and that of cathode are negatively charged during the process of electrolysis of water.

$\huge\mathscr{\underline{\underline{Explanation:-}}}$

In water (pure water) at the cathode, a reduction reaction takes place with electrons that is being given to the hydrogen cations to form the hydrogen gas.

The half reaction, balanced with acid, is :

Reduction at cathode :

2 H+(aqueous) + 2e− → H2(gas)

Whereas, at the anode (positively charged), an oxidation reaction occurs that basically generates the oxygen gas and giving electrons to the anode to complete the circuit :

Oxidation at anode :

2 H2O(liquid) → O2(gas) + 4H+(aqueous) + 4e−

_______________________________

From the above explanations and equations, we can identify that anode during the electrolysis of water is positively charged and that is cathode is negatively charged.
