The colourless species is

Options

  1. AVCl ₃
  2. BVOSO ₄
  3. CNa ₃ VO ₄
  4. D[ V ( H ₂ O )₆ ] SO ₄ H ₂ O

Correct answer

C. Na ₃ VO ₄

Step-by-step solution

In Na ₃ VO ₄ , vanadium is present in +5 oxidation state. V ⁵⁺: 3 d^0 4 s^0 , does not have unpaired electron. Hence, Na ₃ VO ₄ , is colourless species.
