A student develops the list shown below that includes laboratory equipment and materials for constructing a voltaic cell.
Laboratory Equipment and Materials
• a strip of zinc
• a strip of copper
• a 250-mL beaker containing 150 mL of 0.1 M zinc nitrate
• a 250-mL beaker containing 150 mL of 0.1 M copper(II) nitrate
• wires
• a voltmeter
• a switch
• a salt bridge
Complete and balance the half-reaction equation in your answer booklet for the oxidation of the Zn(s) that occurs in the voltaic cell. [1]
