The standard oxidation potential of Zn and Ag in water at 25^(@)C are : Zn(s) toZn^(2+)(aq)+2e^(-), E^(@)=+0.76" V " Ag(s) to Ag^(+)(aq)+e^(-), E^(@)=-0.80" V ". Which of the following reaction will initially take place ?

Answer»

`ZN^(2+)(aq)+Ag^(+)(aq) to Zn(s) +Ag(s)`
`Zn(s)+2AG(s) to 2ZN^(2+)(aq)+Ag^(+)(aq)`
`Zn(s)+2Ag^(+)(aq) to Zn^(2+)(aq)+2Ag(s)`
`Zn^(2+)(aq)+2Ag(s) to 2A^(+)(aq)+Zn(s)`

SOLUTION :(c ) In this reaction, Zn (s) is oxidised to `Zn^(2+)` (aq) IONS and `Ag^(+)` (aq) ions are reduced to Ag (s).
