Problem- A voltaic cell is constructed from an Ni2+(aq)--Ni(s) half-cell and an Ag+(aq)--Ag(s) half-cell. The initial concentration of Ni2+(aq) in the Ni2+--Ni half-cell is [Ni2+]= 1.20X10^-2M . The initial cell voltage is +1.12V.
emf of the cell is 1.08 V.
What is the initial concentration of Ag+(aq) in the Ag+?Ag half-cell?
I have read my textbook moreover I still don't understand so please provide me a very condensed, simple to know answer?
