Which of the following relation is true, if:
Equal amount of charge of electricity in coulomb is passed through aqueous solution of AX and `BX_(2)`.
Number of moles of A and B deposited respectively are Y and Z.

Options

A. Y=Z
B. YgtZ
C. Z=2Y
D. Y=2Z

Answer

D

Explanation

`A^(+)+e^(-)toA`
`B^(2)+2e^(-)toB`
net n coulombs of electricity is passed through the aqueous solution
`:.` no of moles of A deposited = Ymole = n
no of moles of B deposited = n/ 2 = Z mole
`:.(Y)/(2)=Z`
Y=2Z
