For a voltaic (or galvanic) cell using Ag,Ag+ (1.0 M) and Zn,Zn2+ (1.0 M) half-cells, which of the following statements is incorrect?
Select one:
a. The mass of the zinc electrode will decrease as the cell operates.
b. Electrons will flow through the external circuit from the zinc electrode to the silver electrode.
c. Reduction occurs at the zinc electrode as the cell operates.
d. The zinc electrode is the anode
Answers
Answer:
Option c. Reduction occurs at the zinc electrode as the cell operates is the incorrect statement.
Explanation:
An electrochemical cell that transforms the chemical energy of spontaneous redox reactions into electrical energy exists known as a galvanic cell or a voltaic cell. Galvanic cell Voltaic cell exists as an electrochemical cell that makes use of chemical reactions to develop electrical energy.
Silver exists as a chemical element with the symbol Ag and atomic number 47. Categorized as a transition metal, Silver exists as a solid at room temperature.
Zinc exists as a chemical element with the symbol Zn and atomic number 30. Zinc exists as a slightly brittle metal at room temperature and includes a silvery-greyish appearance when oxidation is removed.
Hence, Option c. Reduction happens at the zinc electrode as the cell operates is the incorrect statement.
