Determine electromotive force of the given concentration cell at `25^(@)C`:
`Zn|ZnSO_(4)(0.05M)||ZnSO_(4)(0.5M)|Zn`

What is the emf of the following conc. Cell : Zn//ZnSO_4 (0.05 M) // ZnSO_4 (0.5 M) // Zn

In a concentration cell, Zn|Zn^(2+) (0.1M) || Zn^(2+) (0.15M) | Zn , as the cell discharges:

CuSO_(4)+Zn(s) to ZnSO_(4)+Cu

CuSO_(4)+Zn(s) to ZnSO_(4)+Cu

Represent symbolically the galvanic cells in which the following reaction occurs. Calculate the standard electromotive forces of the cells : (3) Zn+H_(2)SO_(4)rarr ZnSO_(4)+H_(2) Given : E_(Fe^(2+)|Fe)^(@)=-0.44V, E_(Sn^(2+)|Zn)^(@)=-0.14V , E_(Cu^(2+)|Cu)^(@)=0.34V, E_(Zn^(2+)|Zn)^(@)=-0.76V , E_(H^(+)|(1)/(2)H_(2))^(@)=0.00V .

Calculate EMF of following cell at 298 K Zn|ZnSO_(4) (0.1 M) ||CuSO_(4) (1.0 M)|Cu (s) if E_(cell) = 2.0 V
