ELECTROLYSIS

The process of breaking down molten or aqueous solutions into its corresponding ions by the passage of electric current is called

• Electrolysis

• electroplating

• photolysis

• thermolysis

The positive ions are called

• cations

• anions

The negative ions are called

• cations

• anions

The electrode connected to positive terminal of battery is ------- and negative terminal of battery is the -------.

• anode, cathode

• cathode , anode

During electrolysis , oxidation takes place at

• anode

• cathode

At cathode the reaction that occurs is

• oxidation

• reduction

Oxidation is

• gain of electrons

• lose of electrons

Reduction is

• lose of electrons

• gain of electrons

During electrolysis of water the product/products formed is/are
