Question

During the electrolysis of cryolite, aluminium and fluorine are formed in....molar ratio:

1:2
2:3
1:1
1:3

Answer 1

Answer:2:3

Explanation:

Al+3 + 3e- ----> Al (1 mole)

2F- + F2 (1 mole) ----> 2e-

Answer 2

The molar ratio of cryolite aluminum and fluorine during electrolysis are formed in the ratio of 2:3.

The important role in the electrolysis of the aluminum is the electrolyte composition. It is possible to obtain "higher current efficiency" and "lower energy consumption" by modifying the electrolyte composition.

The significant trend towards the reduction of aluminum cells may require higher current efficiency as high current efficiency can bring enormous economic and environmental benefits.
