0.1 Faraday of electricity deposited 2.95 of nickel during electrolysis of an aqueous solution. Calculate the number of moles of nickel that will be deposited by 0.4 Faraday. (ni =58.7)
Accepted Answer
Here's how to solve this problem:
1. Faraday's Law: The amount of substance deposited during electrolysis is directly proportional to the amount of electricity passed through the solution.
2. Calculation: Since 0.1 Faraday deposits 2.95 g of nickel, 0.4 Faraday will deposit four times that amount.
0.4 Faraday
(2.95 g Ni / 0.1 Faraday) = 11.8 g Ni
3. Moles: Convert grams of nickel to moles using the molar mass (Ni = 58.7 g/mol):
11.8 g Ni / 58.7 g/mol = 0.201 moles Ni
Therefore, 0.4 Faraday of electricity will deposit 0.201 moles of nickel.
