The standard oxidation potentials of Zn and Ag in water at 25^(@)C are Zn(s) rarr Zn^(2+)+2e, E^(@)=0.76V Ag(s) rarr Ag^(+)+e, E^(@)= -0.80V Which reaction actually takes place ?

Answer»

`ZN^(2+)(aq.)+Ag^(+)(aq.) RARR Zn(s) + Ag(s)`
`Zn(s) + 2Ag^(+)(aq.) rarr Zn^(2+) + 2Ag(s)`
`Zn(s)+2Ag^(+)(s) rarr Zn^(2+) (aq.) + Ag^(+) (aq.)`
`Zn^(2+)+2Ag^(+)(s) rarr 2A^(+)(aq.) + Zn(s)`
