Q. What is the quantity of electricity (in Coulombs) required to deposit all the silver from 250mL of 1 ${MAgNO}_{3}$ solution?
A) 2412.5
B) 24125
C) 4825.0
D) 48250
Explanation
(b)
250mL of 1 M $AgNO_{3}$ contain $= \frac{250}{1000}$
= 0.25 mole $AgNO_{3}\$
∵ Electricity required to liberate 1 g equivalent of metal
= 96500 C
∴ Electricity required to liberate 0.25 g equivalent of metal
$= \ \frac{96500\ \times 0.25}{1}\$
= 24125 C
