Electrolytic cells and Faraday's law

The anode is where oxidation occurs in...

• A Galvanic Cell

• A Electrolytic Cell

• Both Galvanic and Electrolytic cells

In electrolytic cell which its electrolyte is copper (II) sulphate, copper are used as electrodes. What is the product at the anode?

• Oxygen gas and water
• Copper metal
• Copper (II) ions
• Hydrogen gas

In an electrolytic cell, the positive electrode is the

• anode, where oxidation occurs
• anode where reduction occurs
• cathode where oxidation occurs
• cathode where reduction occurs

What is an electrolytic cell? 

• a cell that converts chemical energy into electrical energy 
• a cell that converts electrical energy into electrical energy 
• a cell that converts electrical energy into chemical energy 
• A cell that converts kinetic energy into potential energy.
