Question

What is the mass of silver deposited on the passage of 2 A current during the electrolysis of silver?
Electrochemical equivalent of silver = $1.18\times {10}^{-3}gm{C}^{-1}$

• A. $2.28\times {10}^{-3}gm$
• B. $2.36\times {10}^{-3}gm$
• C. $2\times {10}^{-3}gm$
• D. $Cannotbedetermined$

Answer 1

The correct option is D $Cannotbedetermined$

We know that faraday's first law states that the Weight deposited is proportional to amount of charge.
W = Z Q
But remember that $Q=I\times t$
$\Rightarrow W=Z\times I\times t$
But we are not given the information for the amount of time the current was passed to determine the charge flowing through. So, the answer cannot be determined.
