(a)
Interpretation:
The oxygen present in air could oxidize the silver metal in the acidic solution or not has to be stated. The balanced cell reaction equation for the corresponding process has to be stated. The standard electrical potential of the cell has to be calculated.
Concept Introduction:
A reducing agent is a reacting species in the reaction that reduces another reacting species. A reducing agent itself gets oxidized when reacts with another species. The reducing agent donates electrons. An oxidizing agent is a reacting species in the reaction that oxidize another reacting species. An oxidizing agent itself gets reduced when it reacts with another species. The oxidizing agent accepts electrons.
(b)
Interpretation:
The oxygen present in air could oxidize the silver metal in the basic solution or not has to be stated. The balanced cell reaction equation for the corresponding process has to be stated. The standard electrical potential of the cell has to be calculated.

- The mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).arrow_forwardAn electrolysis experiment is performed to determine the value of the Faraday constant (number of coulombs per mole of electrons). In this experiment, 28.8 g of gold is plated out from a AuCN solution by running an electrolytic cell for two hours with a current of 2.00 A. What is the experimental value obtained for the Faraday Constant?arrow_forward
