Calculate the mass of sliver fromed in electrolysis by 9650 Coulomb's of electricity
9650 Coulombs is a mole of electrons
this will result in a mole of silver being formed
look up the molar mass of silver
oops. I believe 96,500 coulombs is 1 mole so 9,650 coulombs is 0.1 mole of electrons.
To calculate the mass of silver formed in electrolysis using 9650 Coulombs of electricity, we need to use Faraday's Law of Electrolysis.
Faraday's Law states that the mass of any element formed during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte. The proportionality constant is known as the electrochemical equivalent.
The electrochemical equivalent of silver (Ag) is 0.001118 kg/Coulomb.
Using this information, we can calculate the mass of silver (m) formed by multiplying the quantity of electricity (Q) by the electrochemical equivalent (E):
m = Q * E
Given that Q = 9650 Coulombs and E = 0.001118 kg/Coulomb, we can substitute these values into the equation:
m = 9650 Coulombs * 0.001118 kg/Coulomb
m = 10.7987 kg
Therefore, the mass of silver formed in electrolysis by 9650 Coulombs of electricity is approximately 10.7987 kg.
To calculate the mass of silver formed in electrolysis, you need to know the amount of charge passed through the electrolytic cell and the Faraday's constant.
Faraday's constant (F) is a fundamental constant in electrochemistry. It represents the amount of electric charge per mole of electrons and is approximately 96,485 Coulombs per mole.
First, convert the given charge of 9650 Coulombs to moles of electrons:
Number of moles of electrons = Charge (Coulombs) / Faraday's constant
= 9650 C / 96485 C/mol
= 0.1 mol
Next, you need to determine the stoichiometry of the reaction. Since silver has a 1:1 stoichiometry with electrons (Ag⁺ + e⁻ → Ag), the number of moles of silver formed will also be 0.1 mol.
Finally, use the molar mass of silver (107.87 g/mol) to calculate the mass:
Mass = Number of moles × Molar mass
= 0.1 mol × 107.87 g/mol
= 10.787 g
Therefore, the mass of silver formed in electrolysis by 9650 Coulombs of electricity is approximately 10.787 grams.
