Which of the following represents the lattice structure of A 0 . 95 O containing A 2 + , A 3 + and O 2 – ions? A. B. C.

Options

  1. AB and C only
  2. BB only
  3. CA and B only
  4. DA only

Correct answer

D. A only

Step-by-step solution

Applying the electrical neutrality principle in metal deficiency defect. One A 2 + is missing then two A 2 + ions are converted into A 3 + ion so 0 . 05   A 2 + ion are missing and 0 . 05 × 2 A 2 + ion are converted in A 3 + ion so for each O 2 - ion total A 2 + ion 0 . 85 and A 3 + ion is 0 . 1 . Hence, A satisfies the condition.
