For the following electrochemical cells, calculate the reduction potential and determine if the cell reaction is spontaneous as written.For each reaction, determine the reduction potential of the left and right sides of the cell using the Nernst equation with the standard reduction potential (E°) and given ion concentrations. Then using the sign of the cell potential, determine if the the reaction will proceed as written in a spontaneous fashion.
A voltaic cell is constructed by immersing a strip of silver in a 1.0M AgNO3 solution and a strip of cadmiun metal in a 1.0M Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way. What is the cell potential for t..
