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]
