Question
1. Determine if the following statements are true or false.
True False Standard reduction potential is an intensive property
True False Reduction takes place at the anode
True False The half reaction with the higher standard reduction potential will be at the cathode in a galvanic cell
True False The half reaction with the lower standard reduction potential will be at the cathode in a galvanic cell
2. Evaluate the following questions about line notation.
True False A salt bridge is represented by a single line (|) in line notation
True False The line notation for a cell based on the balanced equation Cu2+ + Zn Zn2+ + Cu would look like this:
Zn | Zn2+ | Cu2+ | Cu
True False The anode electrode is found on the far left position in line notation
True False The anode reagents are found to the right of the salt bridge
3. Evaluate the following questions about inert electrodes.
True False An inert electrode can be used in the anode or cathode (if needed)
True False An inert electrode is needed when there is no conducting solid to attach a wire to
True False Copper metal is often used as an inert electrode
Explanation / Answer
1) - Standard reduction potential is an intensive property True : does not depend upon the amount of matter present
- Reduction takes place at the anode False : At anode always oxidation take place
The half reaction with the higher standard reduction potential will be at the cathode in a galvanic cell True : a higher reduction potential means higher ability to undergoes reduction and hence act as cathode
The half reaction with the lower standard reduction potential will be at the cathode in a galvanic cell False : a lower reduction potential means lower ability to undergoes reduction and easy to gets oxidised and hence act as anode
