Question

The spontaneous reaction that occurs when the cell above operates is: 2Ag^ + + Cd(s) rightarrow 2 Ag(s) + Cd2^ + Select any of choice A - E below to answer questions 1 - 4. Voltage increases. Voltage decreases but remains greater than zero. Voltage becomes zero and remains at zero. No change in voltage occurs. Direction of voltage change cannot be predicted without additional information. Which of the above occurs for each of the following circumstances? The 1M concentration of Cd(NO_3)_2 solution is replaced with a sample of a 0.01 molar Cd(NO_3)_2 solution in the left beaker. The silver electrode is removed from solution. The salt bridge is replaced by a platinum wire Current is allowed to flow for 5 minutes. Tbe initial salt bridge which is NaCl is replaced with CaCl_2. The flow of ions through the solution in a galvanic cell is called a. Galvanic conduction (by Metallic conduction Electrolytic conduction Electrical conduction c. None of the above The batte
