One Faraday of electricity liberates x × 10 – 1 gram atom of copper from copper sulphate, x is______.

Correct answer

0

Step-by-step solution

One Faraday of electricity means it is equivalent to one mole of electrons charge. Cu 2 + + 2 e – → Cu 2 Faraday → 1 mol Cu 1 Faraday → 0 . 5 mol Cu deposit 0 . 5 mol = 0 . 5 g atom = 5 × 10 – 1 x = 5
