In a voltaic cell what is the anode
WebA battery is a set of galvanic cells that are connected together to form a single source of voltage. For instance, a typical 12V lead–acid battery has six galvanic cells connected in … WebHow does Voltaic Cell Work. Usually, in a Voltaic Cell, the anode is made with Zinc (Zn) and the cathode is made with Copper. The anode is immersed in a solution of Zinc Sulfate and the cathode is immersed in a solution of Copper Sulfate. To complete the electric circuit a salt bridge is required here.
