Question

When equal number of coulomb of electricity is passed through aqueous solution of AX and BX₂ and if number of moles of A and B deposited respectively are Y and Z then –

• A. Y = Z
• B. Y < Z
• C. Z = 2Y
• D. Y = 2Z

Answer 1

(d)

Sol. Net n coulombs 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

\ $\frac{Y}{2}$ = Z

Y = 2Z
