In a metal deficient oxide sample, M _ x Y ₂ O ₄ ( M and Y are metals), M is present in both +2 and +3 oxidation states and Y is in +3 oxidation state. If the fraction of M ²⁺ ions present in M is 1 3 , the value of X is ________.

Options

  1. A0.25
  2. B0.33
  3. C0.67
  4. D0.75

Correct answer

D. 0.75

Step-by-step solution

Average oxidation state of M = 1 3 2+ 2 3 3=+ 8 3 aligned & For M _ X M ₂ Y ₄ & 8 3 x +3 2+4(-2)=0 & 8 3 x =2 & x = 3 4 =0.75 aligned
