Vedclass · Answer

(D) According to Faraday's law of electrolysis,the mass deposited $(m)$ is given by the formula: $m = Z 	imes I 	imes t$. Given: Electrochemical equivalent $(Z)$ = $0.126 \ mg/C = 0.126 	imes 10^{-3} \ g/C$. Current $(I)$ = $5 \ A$. Time $(t)$ = $1 \ hour = 3600 \ s$. Substituting the values: $m = (0.126 	imes 10^{-3} \ g/C) 	imes (5 \ A) 	imes (3600 \ s)$. $m = 0.126 	imes 10^{-3} 	imes 18000 \ g$. $m = 0.126 	imes 18 \ g = 2.268 \ g \approx 2.27 \ g$.

The electrochemical equivalent of magnesium is $0.126 \ mg/C$. $A$ current of $5 \ A$ is passed in a suitable solution for $1 \ hour$. The mass of magnesium deposited will be ........... $gm$.
