Card 1Definition of electrolysis

What is electrolysis?

Answer

Electrolysis is the process in which passage of electric current through an electrolyte causes chemical change. Electrical energy is converted into chemical energy. Example: electrolysis of molten sod…

Card 2Electrolytic cell

What is an electrolytic cell?

Answer

An electrolytic cell is a device in which electrical energy is converted into chemical energy through electrolysis. It contains an electrolyte, electrodes, and a battery.

Card 3Types of cells

What is the difference between an electrolytic cell and an electrochemical cell?

Answer

An electrolytic cell converts electrical energy into chemical energy. An electrochemical cell converts chemical energy into electrical energy following redox change. They perform opposite functions.

Card 4Electrodes

Define anode and cathode in an electrolytic cell.

Answer

Anode: the electrode at which oxidation takes place; it is connected to the positive terminal of the battery. Cathode: the electrode at which reduction takes place; it is connected to the negative ter…

Card 5Ions

What are cations and anions?

Answer

Cations are positively charged ions formed by loss of electrons. Anions are negatively charged ions formed by gain of electrons. Cations move towards the cathode and anions move towards the anode duri…

Card 6Migration of ions

Why do cations go to the cathode and anions go to the anode?

Answer

Cations are positively charged, so they are attracted to the negative cathode. Anions are negatively charged, so they are attracted to the positive anode. At the electrodes, cations gain electrons and…

Card 7Redox basics

What is oxidation and what is reduction?

Answer

Oxidation is loss of electrons. Reduction is gain of electrons. In electrolysis, oxidation occurs at the anode and reduction occurs at the cathode.

Card 8Current in electrolysis

Why is electrolysis caused by direct current only?

Answer

Electrolysis is caused by direct current only because a steady current is needed for ions to move in one direction and get discharged at fixed electrodes. Alternating current does not cause electrolys…
