Can a nickel spoon be used to stir a solution of silver nitrate? Support your answer with reason. (E_(Ni^(2+),Ni)^(@)=-0.25V,E_(Ag^(+),Ag)^(@)=+0.80V).

Answer»

Solution :The POSSIBLE REACTION is `Ni+2AG^(+)toNi^(2+)+2Ag`
`E_(cell)^(@)=E_("cathode")-E_("anode")=0.80-(-0.25)=1.05V`
As E.m.f. is positive, reaction is spontaneous.
