Question
Ag+(aq) + Zn(s) Zn2+(aq) + Ag(s)
E°cell = 1.560 V
Choose the label which best describes the following:
A B C D E F G H Direction which anions move through the salt bridge
A B C D E F G H Zn anode
The overall, balanced, spontaneous reaction occurring in this (standard) cell is:
Zn2+(aq) + Ag(s) Ag2+(aq) + Zn(s)
Zn2+(aq) + 2Ag+(aq) 2Ag2+(aq) + Zn(s)
Zn2+(aq) + 2Ag(s) 2Ag+(aq) + Zn(s)
2Ag+(aq) + Zn(s) Zn2+(aq) + 2Ag(s)
False True Tube 'G' hinders Ag+ ions from migrating to the other compartment and reacting directly with the Zn electrode.
False True The solution in tube 'G' must contain an electrolyte for the cell to operate.
False True The salt bridge is labeled 'G'.
False True The salt bridge is intended to allow counter ions to flow between the two cell compartments.
False True The salt bridge disrupts the electrical circuit while permitting mixing of the solutions in the anode and cathode compartments
Ag+(aq) + Zn(s) Zn2+(aq) + Ag(s)
e G D B A FExplanation / Answer
The anions will move towards anode. In this cell Zn is anode, as it is oxidised to Zn^2+
---------------------------------------
Balanced reaction : 2Ag+(aq) + Zn(s) Zn2+(aq) + 2Ag(s)
-----------------------------------
Tube 'G' hinders Ag+ ions from migrating to the other compartment and reacting directly with the Zn electrode.
False :salt bridge is used to maintain the electrical neutrality
------------------------------------
The solution in tube 'G' must contain an electrolyte for the cell to operate.
True
------------------------------
The salt bridge is labeled 'G'.
True
-----------------------------------------
The salt bridge is intended to allow counter ions to flow between the two cell compartments.
False : salt bridge allow the electrons to flow
----------------------------------
The salt bridge disrupts the electrical circuit while permitting mixing of the solutions in the anode and cathode compartments.
False
