What is the equation for Faraday's law of electrolysis?

In summary, the question asks for the current in an electrolytic cell given the mass of gold deposited on the negative electrode and the time period. Using the equations for current and Faraday's law of electrolysis, the solution can be derived by considering the number of electrons per mole of gold atoms.

Homework Statement


If 3.00 10-3 kg of gold is deposited on the negative electrode of an electrolytic cell in a period of 2.62 h, what is the current in the cell during that period? Assume the gold ions carry one elementary unit of positive charge.




Homework Equations


delta Q/delta T
n*q*vd*A: n = moles, q=charge, vd=drift speed and A= cross sectional area of conductor.



The Attempt at a Solution



I'm having a bit trouble starting this because I think we have to derive an equation since we only have mass and the time, and nothing else given. I tried to put the two equations posted together, but it did not look right nor make sense. Can someone give a hint on how to start this?

Google Faraday's law of electrolysis.

But with some thinking you should be able to solve it on your own. There is one electron per atom - how many electrons per mole?

What is a negative electrode?

A negative electrode, also known as an anode, is a terminal in an electrical circuit that has an excess of electrons. It is where the flow of electrons originates.

What is the mass of a negative electrode?

The mass of a negative electrode depends on the material it is made of. It can range from a few grams to several kilograms.

Why is the mass of a negative electrode important?

The mass of a negative electrode is important because it affects the amount of charge that can be stored or released in a battery. A larger mass allows for more charge to be stored, while a smaller mass limits the charge capacity.

How is the mass of a negative electrode measured?

The mass of a negative electrode can be measured using a scale or balance. It is important to take into account the mass of the connecting wires and other components when determining the mass of the electrode.

What materials are commonly used as negative electrodes?

The most commonly used materials for negative electrodes are metals such as lithium, zinc, and cadmium. Other materials such as graphite and carbon can also be used in certain battery types.
