TuteeHUB · Accepted Answer

$$Z{{n}^{++}}(aq)+2Ag(s)\,\to \,2A{{g}^{+}}(aq)+Zn(s)$$

TuteeHUB · Answer

$$Zn(s)+2A{{g}^{+}}(aq)\,\to \,Z{{n}^{++}}(aq)+2Ag(s)$$

TuteeHUB · Answer

$$Zn(s)+Ag(s)\,\to \,Z{{n}^{++}}(aq)+A{{g}^{+}}(aq)$$

TuteeHUB · Answer

$$Z{{n}^{++}}(aq)+A{{g}^{+}}(aq)\,\to \,Zn(s)+Ag(s)$$

1.	The standard oxidation potential of zinc and silver in water at \[298\,\,K\]are \[Zn\,\,(s)\,\,\to \,\,Z{{n}^{2+}}+2{{e}^{-}}\,;\,E=0.76\,V\] \[Ag\,\,(s)\,\,\to \,A{{g}^{2+}}+2{{e}^{-}}\,;\,E=-0.80\,V\] Which of the following reactions actually take place [NCERT 1983, 84; KCET 2003]
A.	\[Zn(s)+2A{{g}^{+}}(aq)\,\to \,Z{{n}^{++}}(aq)+2Ag(s)\]
B.	\[Z{{n}^{++}}(aq)+2Ag(s)\,\to \,2A{{g}^{+}}(aq)+Zn(s)\]
C.	\[Zn(s)+Ag(s)\,\to \,Z{{n}^{++}}(aq)+A{{g}^{+}}(aq)\]
D.	\[Z{{n}^{++}}(aq)+A{{g}^{+}}(aq)\,\to \,Zn(s)+Ag(s)\]
Answer» B. \[Z{{n}^{++}}(aq)+2Ag(s)\,\to \,2A{{g}^{+}}(aq)+Zn(s)\]
