I know that when a voltmeter is removed from the circuit and is replaced by an electrical generator that the reaction will be reversed.
But why is there an increase in mass? Is it because the ion migrate the the copper electrode?
And what is the equation for this reaction?
The question is: 'A student removes the voltmeter from the circuit and replaces it with an electrical generator. the generator causes the copper electrode to increase in mass. Explain, using an equation,why the copper electrod will increase in mass.
This isnt homework...I promise, I simply need to study for an exam that is 2.5 months away and i dont want to get behind.
