Question

use the following information to answer the next question. a student sets up a standard copper - zinc voltaic cell in a laboratory and measures the net potential. compared with solid zinc, solid copper is a _ reducing agent, and during the operation of this cell, the zinc electrode _ electrons. the statement above is completed by the information in row row a b c d i weaker weaker stronger stronger ii gains loses loses gains select one.

Explanation:

Step1: Recall redox - reaction in voltaic cell

In a copper - zinc voltaic cell, zinc is more reactive than copper. Zinc acts as the reducing agent and undergoes oxidation at the anode. Oxidation is the loss of electrons. Copper acts as the cathode where reduction occurs (gain of electrons).

Step2: Analyze reactivity and electron - transfer

Zinc is a stronger reducing agent compared to copper. During the operation of the cell, zinc loses electrons at the anode and copper gains electrons at the cathode.

Answer:

C. stronger, loses
