A) \[51\times {{10}^{-17}}g/C\]
B) \[28\times {{10}^{-6}}g/C\]
C) \[32\times {{10}^{-5}}g/C\]
D) \[47\times {{10}^{-5}}g/C\]
Correct Answer: D
Solution :
From the Faradays electrolysis law, the weight deposited is \[m=z\] it or \[4.5=z\times 4\times 40\times 60\] or \[z=\frac{4.5}{4\times 2400}=47\times {{10}^{-5}}g/C\] (where z is electro-chemical equivalent of zinc)You need to login to perform this action.
