A) 5.6 amp
B) 7.2 amp
C) 8.85 any
D) 11.2 amp
Correct Answer: C
Solution :
Lex x gm of Zn deposite on 9 gm of Hg % of Zn in Amalgam \[=\frac{{{m}_{zn}}\,\times 100}{{{m}_{Zn}}+\,{{m}_{Hg}}}\,\,=\frac{x}{9+x}\,\times 100\,=25\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,x=3gm\] \[Eq.\,of\,Zn\,=\frac{3\times 2}{65.4}\] \[\frac{{{n}_{Zn}}}{1}\,=\frac{{{n}_{{{e}^{-}}}}}{2}\,=\frac{Q}{2f}=\frac{it}{2f}\] Current \[i=\frac{6}{65.4}\,\times \,\frac{96500}{1000}\,=8.85\,amp\].You need to login to perform this action.
