questions?
4. Silver oxide is used in "button batteries to power electric watches and other trinkets. These batteries generate a potential of 1.55 V and consist of a Zn anode and a Ag20 cathode immersed in a concentrated solution of KOH. The cathode reaction is based on the reduction of Ag20 to Ag metal. At the anode, Zn is oxidized to solid Zn(OH)2. Write the net ionic balanced electrochemical cell reaction and calculate the value...
