Chemistry · Electrochemical cells: Electrolytic and Galvanic cells, different types of electrodes, electrode potentials including standard electrode potential, half-cell and cell reactions
The measured potential for \) does not depend upon:
The measured potential for \( M g^{2+}+2 e^{-} \rightleftharpoons M g(s) \) does not depend upon:
- A. raising the temperature
- B. increasing the concentration of \( M g^{2+} \) ions
- C. making the magnesium plate bigger
- D. purity of magnesium plate
Step-by-step solution
The measured potential of a half-cell is an intensive property and does not depend on the size or surface area of the electrode. Temperature and concentration affect the potential via the Nernst equation, and purity can influence the potential if impurities alter the activity or cause side reactions, but the physical size of the electrode does not affect the potential.
