Question
Which of the following represents the lattice structure of A0.95O containing A2+, A3+ and O2– ions? A. | JEE(Main) 2023 | DATE : 01-02-2023 (SHIFT-1) | PAPER-1 | OFFICIAL PAPER | CHEMISTRY PAGE # 4 B. C. (A) A and B only (B) B and C only (C) A only (D) B only
Answer: C
💡 Solution & Explanation
One A+2 is missing then two A2+ ions are converted into A3+ ion so 0.05 A2+ ion are missing and (0.05×2) A2+ ion are converted in A3+ ion so for each O2– ion total A2+ ion 0.85 and A3+ ion is 0.1. For 20 O2– ion total 17 A2+ ion and 2 A3+ ions.
