When equal number of coulomb of electricity is passed through aqueous solution ofAXandBX2and if number of moles ofAandBdeposited respectively areYandZthen -

Options:

Answer:
D
Solution:

A + + e − →A B 2+ +2 e − →B

Letncoulombs of electricity is passed through the aqueous solution

∴no of moles of A deposited=Y mole=n

no of moles of B deposited=n/2=Z mole

∴Y2=Z

Y=2Z
