(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.
Concept Introduction:

Below is just the information I used to get the graphs obtain the graph please help. Prepare two graphs, the first with the percent transmission on the vertical axis and concentration on the horizontal axis and the second with absorption on the vertical axis and concentration on the horizontal axis.
