uestion 18:
alculate the weight of substance deposited when current of 1.5 ampere is passed through solution for 30 minutes. Given ECE=0.000337​

Answer 1

Answer:

Molar mass of Ag =108 g mol−1

1 Faraday =96500 C

Q=i×t=1.5 ×5×60=450 Coulombs

Weight of the substance deposited =ZQ

Z=nFM    n-factor of AgNO3=1

Z=1×96500108

Weight of the substance=96500108×450=965054×90=0.5 g
