A voltaic cell is constructed by immersing a strip of copper metal in 1.0 M CusO, solution and a strip of aluminum in 0.50 M A;(SO4); solution. A wire and a salt bridge complete the circuit. The aluminum strip loses mass, and the concentration of aluminum ions in the solution increases. The copper electrode gains mass and the concentration of ions decreases. Which of the following are applicable to the electrode at which oxidation occurs? II. The cathode II. The positive electrode I. The anode IV. The electrode at which electrons are produced V. The negative electrode a. I, III and V VI. The electrode at which electrons are used up c. II, V and IV b. I, V and VI d. II, III, and IV

Question

Transcribed Image Text:A voltaic cell is constructed by immersing a strip of copper metal in 1.0 M CusO, solution and a strip of
aluminum in 0.50 M Al½(SO4); solution. A wire and a salt bridge complete the circuit. The aluminum strip
loses mass, and the concentration of aluminum ions in the solution increases. The copper electrode gains
mass and the concentration of ions decreases. Which of the following are applicable to the electrode at
which oxidation occurs?
III. The positive electrode
I. The anode
IV. The electrode at which electrons are produced
V. The negative electrode
a. I, III and V
II. The cathode
VI. The electrode at which electrons are used up
c. II, V and IV
d. II, III, and IV
b. I, V and VI
