Question 6 options:
|
Oxidation occurs at the cathode of a galvanic cell. |
|
|
An oxidizing agent is needed to convert CO into CO2. |
|
|
If a species is oxidized, it is formally losing electrons. |
|
|
Electron flow is always from the anode to the cathode in an electrochemical cell. |
|
|
If there are no changes in the oxidation state of the reactants or products of a particular reaction, that reaction is not a redox reaction. |
|
|
For the reaction Fe3+(aq) + Co2+(aq) → Fe2+(aq) + Co3+(aq), Fe3+ is the being oxidized and Co2+ is being reduced. |
