Question

In your words describe what an electrolytic cell is. When characterizing redox reactions, why do we use standard cell potentials, and what are they standard to? Are standard cell potentials written in terms of oxidation or reduction? Use your lecture notes to state the half-cell reaction equation that requires 0.15 V of electricity to occur. Using this reduction half-cell reaction equation answer the following question. How much of the metal, in grams, is deposited onto the electrode if 5.842x10-2 C/s of current passed through the cell for 13 minutes and 5 seconds?

Answer 1

A):An electrolytic cell is a device that converts the electrical energy of to chemical energy by driving a non spontaneous reaction in a cell.

B):We use standard cell potential as a reference to make calculation easier and a Mark of reference.

C):They are standard w.r.t the potential of hydrogen electrode.We see how much greater is the potential of an electrode to that of hydrogen electrode which is been assigned as 0.

D):They are generally written in terms of reduction potential unless mentioned otherwise.
