\(Ag\) નુંવજન \(= 108/1 = 108\) ; \(Cu\) નુ વજન \(= 63.6/2 = 31.8\)
\(M_1/M_2 = E_1/E_2 ⇒ 10.79/M_{cu} = 108/31.8 M_{cu} = (10.79 × 31.8) / 108 = 3.2 gm.\,\)
$A$. $\mathrm{Fe}$ $B$. $\mathrm{Mn}$ $C$. $\mathrm{Ni}$ $D$. $\mathrm{Cr}$ $E$. $\mathrm{Cd}$
Choose the correct answer from the options given below:
$Fe_{(aq)}^{3 + } + {e^ - } \to Fe_{(aq)}^{2 + }$ ; ${E^o} = 0.771{\mkern 1mu} \,volts;{\mkern 1mu} $
${\mkern 1mu} {I_{2(g)}} + 2{e^ - } \to 2I_{(aq)}^ - \,;{\mkern 1mu} $ ${E^o} = 0.536{\mkern 1mu} \,volts$
કોષ પક્રિયા $2Fe^{3+}_{(aq)} + 2l^{-}_{(aq)} \rightarrow 2Fe^{2+}_{(aq)} + I_{2(g)}$ માટે $E^o_{cell} = ….$
