Calculate the number of Faraday`s of electricity required to deposit 60 grams of megnesium
1 Answer
Chhavi Jain
Dear student ,
Mg2+ + 2e- -----> Mg(s)
2 mole electrons are required to deposit ---->24 grams of Mg
or in other words
To deposit 24g of Mg ----> 2 mole electrons are required or 2F charge is required
So, to deposit 60g of Mg -----> (2F /24) * 60 charge is required
------> 5 Faraday (F) charge is required
