Hello everyone. I am having trouble with a question on electrochemical cells. I have to find the balanced REDOX reaction of the cell. All I am given is a diagram with the following information 1. Aluminum electrode submerged in 1 mol/L Aluminum Nitrate Al(NO3)3(aq) 2. Nickel electrode submerged in 1 mol/L Nickel Nitrate Ni(NO3)2(aq) 3.There is a salt bridge KNO3(aq) With this information I stall because I cant figure out which one is the cathode, and which one is the anode. I know that NO3 is a polyatomic ion with a charge of -1 so that would make Al+3, and Ni+2. How do I figure out which one is being oxidized, and which one is being reduced? If I knew that then I would be able to balance the reaction. Please help me I tried many things, and can't figure it out. My notes don't tell me either so I am guessing its common knowledge that I missed out on.
