Question

1. Write the net ionic equations that occur in the followingcells: Pb|Pb(NO3) ||AgNO3|Ag Zn|ZnCl2||Pb(NO3) |Pb Pb|Pb(NO3) ||NiCl2|Ni

Explanation / Answer

Pb -> Pb2+ +2e- 2Ag+ + 2e- --> 2Ag ---------------- Pb+2Ag+ ---> Pb2+ +2Ag --------------------------------------------------------------- Zn -----> Zn 2+ +2e- Pb2+ +2e- ----> Pb -------------------------- Zn +Pb2+ --------> Zn2+ + Pb --------------------------------------------------------------------- Pb --->Pb2+ +2e- Ni2+ +2e- ----->Ni -------------------------- Pb +Ni2+ --> Pb2+ +Ni
