The standard oxidation potential of Zn and Ag in water at 20^(@) C" are: " Zn(s) rarr Azn^(2+) (aq) + 2e^(-) E^(o) = 0.76 V Ag(s) rarr Ag^(+)(aq) +e^(-) E^(o) = - 0.80 V Which one of the following reactions actually takes place?

Answer»

`Zn(s) + 2 Ag^(+)(aq) RARR Zn^(2+) + 2 Ag(s)`
`Zn^(2+) (aq)+2AG(s) rarr 2Ag^(+)(aq)+ Zn(s) `
`Zn(s) + Ag(s) rarrZn^(2+)(aq)+Ag+(aq)`
`Zn^(2+)(aq)+Ag^(+)(aq) rarr Zn(s)+Ag(s)`
