Question
A standard cell has all reactants and products present at an activity of 1. This means that all aqueous species must be present at 1 M concentrations and all gases present at 1 atm pressure. If solids act as either reactants or products, they must also be present In lab, you will be given an unknown metal, M, and a 1.0 M solution of its ion, M*+to identify. You will also have a copper electrode and 1.0 M solution of Cu2+ In this practice experiment, you will have piece of silver (Ag) and a 1.0 M Ag+ solution, something we could never afford to do in real life Your unknown will be one of the other metals listed in the table below half-reaction 15° (V Ag+ + e- Ag +0.80 Fe3+ + 3e- Fe 1-0.036 Pb2+ + 2e- Pb | -0.13 Al3+ + 3e- Al | -1.66 Mg2+ + 2e- Mg -2.37 Taking into account the standard reduction potentials of these metals, fill in the components of a standard cell in the line notation below. The anode is on the left. It should contain the species with the lowest reduction potential. Fill in the correct components in the diagram for a standard cell Ag (s) M (s) C (s) Ag+ (1.0 M) Mx+ (1.0 M) KNO3 eaction Mx+ (1.0 M)I need a soluble oxidation reaction. KNO3 C (s) anode, so you This is the anode. You This is the cathode. You This is the cathode. You that is the oxidation component of the need a soluble component of the reduction reaction. need a solid that is involved in the reduction reaction Submit Answer Incorrect.

Answer:-
In the standard cell , reduction occurs on the right.i.e, cathode and oxidation on the left.i.e, anode. So the standard cell is represnted as follows,
M (s) | Mx+(1.0 M) || Ag+ (1.0 M) | Ag (s)
