A 110 watt, 110 volt lamp is connected in series with an electrolytic cell containing C d S O 4 . What mass of cadmium will be deposited by the current flowing for 10 hour? (Atomic mass of Cd = 112.4)

Options

  1. A20.96 g
  2. B91 g
  3. C17 g
  4. D26 g

Correct answer

A. 20.96 g

Step-by-step solution

P = VI I = P V = 110 110 = 1 Equivalent mass of Cd = A t o m i c m a s s V a l e n c y = 112.4 2 = 56.2 W = I t E 96500 = 1 × ( 10 × 60 × 60 ) × 56.2 96500 = 20 . 96 g .
