Question

How many Faradays are required to generate one gram atom of Mg from MgCl2?

Answer 1

Answer:

2 Faradays

Explanation:

so, it is clear that one mole of magnesium is formed by two moles of electrons. so, two moles of electrons are equivalent to 2 Faradays of charge. Therefore 2 Faradays are required to generate one gram atom of magnesium from MgCl₂.

Answer 2

Answer :-

We know that one gram atom = 1 mole

${Mg}^{2 + } + {2e}^{ - } - > Mg$

1 gram of atom or 1 mole of Mg requires 2 electrons.

We know that,

Nunber of electrons = number of Faradays

Therefore, Number of Faradays = 2

Hope the answer helps you.
