A redox reaction occurs in an electrochemical cell, where Ag is oxidized and Ni is reduced. Write a half reaction for this reaction indicating the half reaction oxidized and half reaction reduced. What is the anode and cathode. Calculate the standard voltage of the cell. What kind of electrochemical cell is it?

Expert Answers

An illustration of the letter 'A' in a speech bubbles

In voltaic cells, also called galvanic cells, oxidation occurs at the anode and reduction occurs at the cathode. A mnemonic for this is "An Ox. Red Cat." So since silver is oxidized, the silver half-cell is the anode. And the nickel half-cell is the cathode. 

Another mnemonic is "OIL RIG". Oxidation Is Loss. Reduction Is Gain (of electrons)....
