The standard reduction potentials of Zn and Ag in water at 298K are. `

1.	The standard reduction potentials of Zn and Ag in water at 298K are. `Zn^(2+)+2e^(-)hArrZn,E^(@)=-0.76V` and `Ag^(+)+e^(-)hArrAg:E^(@)=+0.80V` Which of the following reactions take place?A. ` Zn^(2+)(aq)+Ag^(+)(aq)rarrZn(s)+Ag(s)`B. `Zn(s)+Ag(s)rarrZ^(2+)(aq)+Ag^(+)(aq)`C. `Zn^(2+)(aq)+2Ag(s)rarr2Ag^(+)(aq)+Zn(s)`D. `Zn(s)+2Ag^(+)(aq)rarrZn^(2+)(aq)+2Ag(s)`
Answer» Correct Answer - D More the R.P. easier to reduce. Thus `Ag^(+)` will be reduced and Zn will be oxidised. `Zn(s)+2Ag^(+)(aq)rarrZn^(2+)(aq)+2Ag(s)`
