reduction electrode is:

• cathode

• anode

What is Faraday's first law of electrolysis?

What is Faraday's second law of electrolysis?

One Faraday is:

• The amount of charge carried by 1 mole of electrons

• the amount of charge carried by 1g of electrons

• the amount of charge carried by 1 electron

• the amount of charge carried by 1 Kg of electron

The correct relation between Avogadro's number and Faraday's constant is:

• W= EIt/F

• F= WIt/E

• F= WItE

• W= FIt/E

What is a galvanic cell?

• A type of battery that stores energy chemically due to electrical energy

• A device used to measure electrical conductivity of an electrolyte

• A tool for analyzing gas composition
• A cell that converts chemical energy to electrical energy due to spontaneous redox reactions.

What is electrode potential?

• Electrode potential is the measure of the amount of ions in an electrode when in contact with a solution of its own ions.

• Electrode potential is the measure of the temperature of an electrode.
• Electrode potential is the measure of the color of an electrode.
• Electrode potential is the measure of the tendency of an electrode to gain or lose electrons in contact with a solution of its own ions.
