Chemistry Class 11 NCERT Solutions: Chapter 8 Redox Reactions Part 15
Q: 29. Given the standard electrode potentials,
Arrange these metals in their increasing order of reducing power.
The lower the electrode potential, the stronger is the reducing agent. Therefore, the increasing order of the reducing power of the given metals is
Q: 30. Depict the galvanic cell in which the reaction takes place, further show:
(i) which of the electrode is negatively charged,
(ii) the carriers of the current in the cell, and
(iii) individual reaction at each electrode
The galvanic cell corresponding to the given redox reaction can be represented as:
(i) electrode is negatively charged because at this electrode, oxidizes to and the leaving electrons accumulate on this electrode.
(ii) Ions are the carriers of current in the cell.
(iii) The reaction-taking place at electrode can be represented as:
And the reaction-taking place at Ag electrode can be represented as:
