2. 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 Al-(SO.), 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 copper ions decreases. Which of the following are applicable to the copper electrode? L. I. The anode The cathode III. The positive electrode The electrode at which electrons are produced The negative electrode VI. IV. V. The electrode at which electrons are used up I, II, and V b. I, IV, and V II, IV, and V d. a. C. II, III, and VI None of the first four responses contains all the correct choices and no others. e. fiaiant of S?

A chemist designs a galvanic cell that uses these two half-reactions:

Give two suggestions to prevent corrosion Name two differences between galvanic (voltaic) cells and electrolytic cells. What is corrosion?  Define and give an example

Which of the following is the purpose of a salt bridge in an electrochemical cell? a. Stabilization of precipitates that may form during the redox reaction. b.Allowing the electrons to directly flow from anode to cathode. c. Providing electrons that react at the surface of the anode and cathode. d. Maintaining electrical neutrality by allowing ions to migrate.
