When the ion Cr 2 O 7 2 - acts as an oxidant in acidic aqueous solution the ion Cr 3 + is formed. How many moles of Sn 2 + would be oxidised to Sn 4 + by one mole of Cr 2 O 7 2 - ions?

Options

  1. A2/3
  2. B3/2
  3. C2
  4. D3

Correct answer

D. 3

Step-by-step solution

Cr 2 6 + + 6 e → 2 Cr 3 + × 1 ; Sn 2 + → Sn 4 + + 2 e × 3
