Faraday's First Law

Q.

The amount of electricity that can deposit 108g of silver from ${\mathrm{AgNO}}_3$ solution is?

Q.

In an electroplating experiment m g of silver is deposited, when 4 amperes

of current flows for 2 minutes. The amount (in gms) of silver deposited by 6

amperes of current flowing for 40 seconds will be

[MNR 1991]

1. 4 m

2. m/2

3. m/4

4. 2m

Q. The mass of the ion deposited by passing a current of one Ampere for one second is called the ___ equivalent.

Q. The transport no. of $A{g}^{+}$ ion in $AgN{O}_3$ is 0.48. The equivalent conductivity of $AgN{O}_3$ at infinite dilution is $120Sc{m}^{-1}e{q}^{-1}$.

Q.

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

1. $Cannotbedetermined$
2. $2.28\times {10}^{-3}gm$
3. $2.36\times {10}^{-3}gm$
4. $2\times {10}^{-3}gm$
