Question

Describe galvanic cells that use the following reaction. Label the anode and cathode, identify the sign of each electrode, and indicate the direction of electron and ion flow.
Pb(s)+2H+(aq)Pb2+(aq)+H2(g)

Drag the appropriate labels to their respective targets. Note: not all labels will be used. simply tell me whats what and how is the flow of electrons.

A) Pb(s)+2H+(aq)Pb2+(aq)+H2(g)
Write the anode half-reaction.

B) Pb(s)+2H+(aq)Pb2+(aq)+H2(g)
Write the cathode half-reaction.

and lastly similar to the first labeling quesion

[[ Describe galvanic cells that use the following reaction. Label the anode and cathode, identify the sign of each electrode, and indicate the direction of electron and ion flow.
Cl2(g)+Sn2+(aq)Sn4+(aq)+2Cl(aq) ]]

Explanation / Answer

for the reaction

Pb(s)+2H+(aq)Pb2+(aq)+H2(g)

anode 2H+(aq) + 2e- -------------- H2(g)

cathode   Pb(s) ------------------- Pb2+(aq) + 2e-

2)

for the reaction

Cl2(g)+Sn2+(aq)Sn4+(aq)+2Cl(aq)

cathode Sn2+(aq) ------------------ Sn4+(aq) + 2e

anode   Cl2(g) + 2e- ------------------ 2Cl(aq)
