Calculate the emf of the cell : Mg|Mg^(2+)(0.1 M)||Ag^(+)(1.0xx10^(-3) M)|Ag Given that E_(cell)^(@)=3.15" V".

Answer»

SOLUTION :`E_(cell)^(@)=E_(cell)^(@)-(0.0591)/(n)"LOG"([MG^(2+)])/([Ag^(+)]^(2))`
`=3.15-(0.0591)/(2)"log"(0.1)/((1.0xx10^(-3))^(2))`
`=3.15-0.02955" log "5`
`=3.15-0.02955xx0.6989`
`=3.15-0.0207=3.13~~3.0`
