Anode is positively charged
Hence it attracts the negative charge towards it
It means oxygen has the valency as -2
Therefore oxygen is released at anode during electrolysis process

HERE'S YOUR ANSWER.......✌️✌️
ANSWER;
Positively charged ions move to the negative electrode. Metal ions are positively charged, so metals are produced at the negative electrode (cathode).
Negatively charged ions move to the positive electrode. Non-metal ions, such as oxide ions and chloride ions, are negatively charged, so gases such as oxygen or chlorine are produced at the positive electrode (anode).
