How many coulombs of electricity would liberate 1.08g of Ag from a solution of silver salt?

[Ag = 108.0; 1F = 96500 C]

Answer Details

To calculate the number of coulombs of electricity required to liberate 1.08g of Ag from a silver salt solution, we need to use Faraday's laws of electrolysis, which state that the amount of a substance produced by electrolysis is directly proportional to the quantity of electricity passed through the electrolyte.
The formula for calculating the amount of electricity required to liberate a certain amount of a substance is:
Quantity of electricity = (Mass of substance / Equivalent weight) × 96500
The equivalent weight of Ag is equal to its atomic weight divided by its valency. Since the valency of Ag is 1, the equivalent weight is equal to its atomic weight, which is 108.0 g/mol.
Using the above formula, we get:
Quantity of electricity = (1.08 g / 108.0 g/mol) × 96500 C/mol
Quantity of electricity = 965 C
Therefore, the number of coulombs of electricity required to liberate 1.08g of Ag from a silver salt solution is 965 C.
In summary, option C is the correct answer.
