Quantitative Aspects of Electrolysis Flashcard

Front

What is electrolysis?

Back

Electrolysis is a chemical process that uses electrical energy to drive a non-spontaneous reaction, typically used to decompose compounds into their elements.

Front

Which metal is commonly extracted using electrolysis?

Back

Aluminium is typically extracted using electrolysis.

Front

What gas is produced at the anode during the electrolysis of aqueous sodium chloride?

Back

Chlorine gas is produced at the anode during the electrolysis of aqueous sodium chloride.

Front

What does Faraday's First Law state?

Back

Faraday's First Law states that the mass of a substance produced at an electrode during electrolysis is proportional to the quantity of electricity passed.

How many moles of silver are deposited when 96500 Coulombs of charge is passed through a solution of silver nitrate?

Back

1 mole of silver is deposited when 96500 Coulombs of charge is passed through a solution of silver nitrate.

Front

What is the formula to calculate the amount of substance deposited during electrolysis?

Back

The formula is Mass = Q/nF, where Q is the charge, n is the number of moles of electrons, and F is Faraday's constant.

Front

What is Faraday's constant?

Back

Faraday's constant (F) is approximately 96500 Coulombs per mole, representing the charge of one mole of electrons.

Front

What is the role of the anode in electrolysis?

Back

The anode is the electrode where oxidation occurs, and it is where positive ions migrate to gain electrons.

Front

What is the role of the cathode in electrolysis?

Back

The cathode is the electrode where reduction occurs, and it is where negative ions migrate to lose electrons.

Front

What is the significance of the quantity of electricity in electrolysis?

Back

The quantity of electricity passed during electrolysis determines the amount of substance produced at the electrodes.
