Question

Electrolysis of water gives dioxygen gas - True or False?

• A. True
• B. False

Answer 1

The correct option is A True

In an electrolytic setup anode is the place where oxidation takes place and cathode is the place where reduction takes place. $O^{-2}$ looses two electrons at the anode to form oxygen, where as $H^{+}$ gain electron at the cathode to form hydrogen gas.
Oxidation is nothing but loss of electrons and reduction is nothing but gain of electrons.
Electrolysis of water gives oxygen $\left(O_2\right)$ gas at anode and hydrogen $\left(H_2\right)$ gas at cathode and it can be separated and stored in cylinders
