When equal number of coulomb of electricity is passed through aqueous solution of A X and B X 2 and if number of moles of A and B deposited respectively are Y and Z then -

Step-by-step solution

A + + e − → A B 2 + + 2 e − → B Let n coulombs of electricity is passed through the aqueous solution ∴ n o o f m o l e s o f A d e p o s i t e d = Y m o l e = n n o o f m o l e s o f B d e p o s i t e d = n / 2 = Z m o l e ∴ Y 2 = Z Y = 2 Z
