Question

Introduction to Galvanic Cells Learning Goal: To understand the components and processes of a galvanic cell. A galvanic cell (or voltaic cell) produces electricity using a spontaneous redox reaction, such as the one shown here: The components of this reaction are separated by a salt bridge and connected with a wire, forcing the electrons to travel across the wire, creating electricity. Part A Describe the electrodes in this iron-copper galvanic cell. Drag the appropriate items to their respective bins.

Explanation / Answer

in galvanic cell oxidation happens at anode and loose its mass, reduction happens at cathode and gains mass.    . in above cell Fe involves oxidation so Fe act as a anode. Cu+2 involves in reduction so Cu act as cathode,

anode =Fe cathode =Cu        

loose the mass    gain the mass
